Course to Venus Solution: Where to Start

The main progression in Course to Venus follows a chain of ship investigations, crew conversations, and relationship events. When an interaction only produces a repeated standard message, the usual solution is to complete another available quest first rather than repeatedly clicking the same location.

The game is a humorous, adult-oriented space adventure focused on choices, relationships, and a dysfunctional crew. The official Course to Venus page on itch.io lists the project as in development and identifies the available release as version 0.5.3 for supported platforms.

Advance Other Quests

Complete open conversations and location objectives before returning to a blocked clue. Several interactions unlock only after another quest is resolved.

Check the Ship at Night

Nighttime changes which objects and events can be inspected. Use the correct tool instead of relying only on daytime clicks.

Follow Character Choices

Relationship scenes depend on dialogue decisions. Choose responses that fit the Captain when a specific character route is required.

Mature Content

Course to Venus is intended for adults and contains mature themes. Follow the creator's content guidance before playing, and do not treat relationship scenes as separate objectives unless the story requests them.

Vent Key and Ship Investigation Walkthrough

The vent sequence is one of the most frequently requested solutions. The key does not appear as a normal inventory item at the beginning. First, progress far enough to receive the quest that makes the Captain investigate the ship. Interact with the vent during that quest to trigger the next clue.

1

Unlock the Search Quest

Continue the available story and crew objectives until the Captain receives the quest to search the ship. If the vent only gives a standard response, the investigation has not advanced far enough.

2

Inspect the Vent

Tap or select the vent during the active search quest. This interaction causes the Captain to wonder how it can be opened and updates the search objective.

3

Search the Fridge at Night

Visit the fridge after nightfall. A black lunch box should become available once the correct quest state is active. Open it to obtain the vent key.

4

Return to the Vent

Use the key on the vent and continue the resulting scene. If the lunch box is missing, return to other open quests and check the fridge again later.

The timing matters more than the number of clicks. A missing black lunch box usually means the search quest has not been triggered, not that the save file is necessarily broken.

Fastest Fix for a Missing Key

If the black lunch box does not appear, stop searching the fridge repeatedly. Tap the vent during the ship-search quest, then revisit the fridge at night.

Motion Sensor, Clues, and Ghost Investigation

The motion sensor is essential for the nighttime investigation. After receiving it from Amy, use it in every room and major location on the ship rather than waiting for a single obvious event. The objective is designed around checking the ship systematically.

If the clue search appears stuck, progress through other quests first. In particular, the lounge must be unlocked before watching TV there can provide the required story progress. The investigation may not advance until these prerequisite scenes have been completed.

Investigation Checklist:

  • Receive the motion sensor from Amy
  • Visit every accessible ship location at night
  • Use the sensor in each room
  • Unlock the lounge and watch TV
  • Return to the investigation objective after completing other quests
Investigation Route

Treat the sensor as a room-by-room tool. Check every accessible area at night, then review the lounge and TV objective before assuming the mission is blocked.

Every ship roomDuring the active investigationPrevents missed nighttime triggers
LoungeAfter unlocking itEnables the TV-related progression
TVAfter entering the loungeHelps reveal the required clues
VentDuring the ship-search questStarts the key sequence

Do not confuse optional character scenes with mandatory investigation steps. A bath event, a relationship conversation, or a route-specific interaction may appear while exploring, but it may not be required for the central clue chain.

Ice Trading and Relationship Progression

The ice objective requires two separate steps: locate an iceberg through the cruise ship and deliver the collected ice to the correct vessel. Helping the cruise ship several times can provide coordinates to an iceberg in space. After collecting the ice, return to the Indestructible 4 to trade it.

This objective can feel unfinished because collecting the ice is not the final action. The trade occurs after returning to the ship connected to the objective. If the game still shows no result, confirm that the ice is in the current save and that you returned to the correct location.

Cruise Ship

Help with its available requests to receive information leading to the iceberg coordinates.

Iceberg Location

Travel to the provided coordinates and collect the ice needed for the trade objective.

Indestructible 4

Return here with the ice to complete the exchange and advance the related objective.

Relationship progression also affects how much content is available with each crew member. The currently reported maximum relationship level is 4. Dialogue choices should match the Captain's personality when a route asks for a specific type of response.

Progression Check

For the ice quest, the correct order is: help the cruise ship, travel to the iceberg, collect the ice, then return to the Indestructible 4 and trade it.

Troubleshooting and FAQ

Use this final checklist before restarting a scene or exporting a save. Most apparent blocks come from quest order, time of day, or returning to the wrong ship location.

  • Confirm that the relevant quest is active.
  • Check whether the required interaction is nighttime-only.
  • Complete every currently available conversation.
  • Revisit the lounge after unlocking it.
  • Return to the objective location after collecting a required item.
Save Management Tip

Keep a separate save before major relationship decisions and investigation milestones. This makes it easier to test dialogue choices without losing earlier progress.

Q: What is the Course to Venus solution for the vent key?

Progress until the ship-search quest appears, inspect the vent during that quest, then search the fridge at night for the black lunch box containing the key.

Q: Why is the black lunch box missing from the fridge?

The story may not have reached the required quest state. Continue other objectives, inspect the vent during the ship-search quest, and check the fridge again at night.

Q: How do I find the investigation clues?

Use the motion sensor in every accessible ship location at night. Also unlock the lounge and watch TV, because those scenes can be required for the investigation to advance.

Q: What do I do with the ice?

Help the cruise ship to obtain iceberg coordinates, collect the ice, then return to the Indestructible 4 and trade it there.
