congrats on submitting! I gather from your itch page you're fairly new to game dev so it's an accomplishment to get anything submitted for a jam this quick. I have two suggestions for you to look into for future growth:
- Research color theory
- understanding and applying color theory well will do more for your visuals than almost anything else
- do a deeper dive into your tools
- for example: I noticed your logo appears a bit blurred. In Unity you need to disable a particular filter in order to fix that problem with pixel art. idk what tool you used but make sure you know those options and how to turn them on
Best of luck on your game dev journey! Keep it up!!
