Based on what I played, I'm going to treat this one as a demo/prototype.
I liked the artwork! It had a bright, loose style that was charming. I do wish there were subtitles/text to explain what was happening in the story. I actually missed it the first time around, because the text told me to press spacebar. Then I replayed and realized that I had skipped all the story scenes... whoops!
The gameplay itself is a good start. A sort of whack-mole concept. I played with a mouse, but it would work well on a touch screen! It could use a little more variety, but again, I realize this is a demo not a final project. I did have the weird issue of a large grey area on the screen that seemed outside the playing field, but then a mouse spawned there.
One other stray issue I noticed was that the audio seemed like it was on a mono channel... I only heard it in my left headphone.
This is a good start, and with a little more work and polish, it should all come together. Nice work!
