Yo, this is very well-polished for being a first attempt, so great work!
Played around and the style and tilemaps are pretty well done, especially the menu interface.
A thing to make it even better would've been to make the main functions of the game easy to understand from the game itself.
At first when I started playing I didn't understand how to suck the dirt, I just thought that walking over it would've been enough but that wasn't it.
I also almost missed that it's possible to get upgrades because there's only a button in lose menu that didn't tell me they were there since it's unlabeled. Good thing I read the game description here!
Good thing you did add them though, I played a little bit more than I thought I would thanks to them.
The music was also pretty pleasant, and the sound effects between gameplay and UI were nicely chosen!
Once again great work, best of luck for the future!
