How can I improve?
List of problems/comments:
- Corner tiles need to be "square" because of the way the physics engine is designed.
- I don't like the player's tail. How can I make it look better?
A game with a very simple visual style and a small palette can work, but you have to give the player something to look at. There has to be some charm to be found somewhere. I would suggest giving your characters fluid, overstated animations. It would be extremely easy given your character sprites, and would give us something pretty to watch. Also, if you're going to make a game grey, be sure there's a
reason it's grey. You want players to become immersed in the visual style, not just think you're lazy.
Good luck!
