I recently created a game for my brother’s birthday, not really meant for anyone else to see it but him. I spent a lot of time on the 2D assets, intending to use them on my next game project.
In the game you controlled an astronaut, and could get into a vehicle, drive the vehicle and collect items (for the inventory I used an asset called S-Inventory), then deliver them to NPCs (I used a quest system called S-Quest). Then near the end of the game, you could get out of the van, and get into a spaceship which was controlled similar to my Starbug Thruster game.
Here’s some videos.
Here’s some early experiments with the ragdoll astronauts:
