Loved the style! It's really aesthetically pleasing. All the effects are perfectly suited for each other, too.
The gameplay is fun, too! But are the enemy placements random? There are a lot of times where I could have sworn the patterns were different between different attempts. Sometimes I faced huge challenges that I was preparing to have to work really hard to solve, but then on the next attempt the enemy placement would give me no challenge at all. I really think that the game would have benefitted from manual enemy placements. But the game offers a fun challenge nonetheless, so I enjoyed it a lot overall :)
I think this game would work really well if adapted to a mobile game. But I know nothing of marketing mobile games, so I'll let you be the judge of that!
Good job!
