The core concept of the game has a lot of potential! I have some feedback for you if you are going to continue working on this game.
What you did well:
- Again, the core concept is very cool. There is a good chunk of platformers that allow you to flip the player gravity, but not the entire room's gravity.
- Very simple, easy to grasp the controls and objective!
- Having the game force a spin after you grab a coin adds a bit more spice to it!
Suggestions:
I will throw a lot of suggestions at you since I think there is a ton of ways this game can be expanded!
- Giving the player some way to control the direction the level spins would be very good, as the player can just control where they land either way by spamming the button.
- Have checkpoints between levels, or at least at the 2nd level.
- For a more long-term build, you could use this flipping mechanic to do things like making boxes that block a path go out of the way, or even moving around liquid!
- Additionally, environmental hazards could be pretty cool, and they could also harm enemies too, allowing you to deal with enemies in really annoying spots.
- More specific objectives? Like maybe for one level you have to get the coins in a specific way, or for another level you have to actually kill an enemy or two.
