It’s a nice little fun game, it’s simple but works well and it’s just fun to rack up a high score. The art and music are also nice.
The buff/debuff system doesn’t seem as prominent as it should be though. I’m not exactly sure what any of them did and without any feedback beside the new icon popping up, I didn’t even realize when I was getting anything new. A description of the types of effects somewhere and/or a stronger notification like a sound when you gain an effect would have been nice. I also agree with comments below that the challenge didn’t increase too much over time, so eventually it didn’t feel as interesting to keep going. I like the suggestion of having more taiyaki in the waves, would have been an interesting diifficulty increase.
Regardless, very fun, great job on the game!
