This is a really quick game for sure. Feel nice though. The pixel art is really nice and I like it very much too. I'd say the game does need something to give the player a challenge (even just slight), for something simple enough, just do a countdown timer that affects the score would be nice. Also, traps and bottomless pits would be nice and quick, you get the idea. It's also quite a bummer that the game is so zoomed in, yet the resolution is that small. I am guessing this is a wrong setting idk.
Anyway, hope you have fun making games and keep up the good work!
