Thank you! I agree that it would be cool to explore a similar world with more variety and things to discover. You might want to check out the game "No Parachute" which was an inspiration for our game.
If you ever make this game let me know!
Also don't hesitate to ask if you have any technical questions about how we made the game (it is actually relatively easy to make a "3d" game like that from scratch, as everything is flat)
