This is quite a simple and easy to understand game, it's quite fun too. Love the artwork, the pixel art is really charming and joyful. The music is also nice. Is the music speeding up while you're playing? At least it felt like it. The gameplay is a standard collect dropping item game, and it's quite well make. The dash ability and the different cookies add quite a bit of variety and certainly improve the game a lot. Nice job! I've played to around 141 points, sadly, can't make it onto the leaderboard though.
For some criticism, I'd say during the late game, getting hit once means half your health is gone, thanks to you can't even move until the iframes are gone. That felt a bit unfair ngl. I would also suggest putting in the item effect description in the game itself, not just on the itch page. That way players who don't read the jam page still get an idea what is what, and make the overall experience a smoother one.
Anyway, good job on making this game. Keep up the good work!
