Excellent! Game looks super cute. The celebration animation is particularly good. Feels great to play, getting a big combo was fun. I got to level 4, and the difficulty curve was great. Always felt engaged and challenged. I liked that you could hit the enemies with your ball.
A few things that might improve it:
Like crab said, some skid when you swing would be really good. Get some juice on destroying the blocks. It's the most fundamental thing you do and should feel awesome when you blast one, and 10x as awesome when you have a big combo going. I had trouble getting use out of the slide. Once there were a lot of enemies, it was somewhat useful in getting through their projectiles. But I still feel it could be much more fun and useful. What if it also functioned as a hit, or you could hit while sliding. Sliding into the ball to catch it just in time and keeping your combo going would be amazing. What if you could hit the projectiles to dissipate them?
Keep up the great work!
