Hello. Professional dev here. I don't have any on itch.io yet, and I don't practice game development often.
Wanted to say that the thing itself is really cool, especially if you're 12 year old, so keep going (I wish I started that early), tho wanted to highlight controls. Controls are the most important thing in the game: if they feel bad, the game (even if it's good) will not keep the player interested. I recommend making international game controls so the controls would be easy to understand. Example:
[A and D] or [LEFT ARROW and RIGHT ARROW] to move
[W, SPACE or UP ARROW] to jump
[S or SHIFT] to dash
[X or E] to interact
These all are from big games (like Super Mario Bros.), so the player will understand them more. Recommend making multiple key binds for each movement action.
