I think the idea has great potential. It's a lot of fun as it is but there are quite a lot of scenarios where losing just felt "unfair". The basic idea is great though and I'd love to play a game with that and a little more room to dodge stuff. :)
I agree. I was so happy to have finished it that I just released it with a lot of timers left, but I think I should have spent a little more time on balancing it. For example, the hitboxes in boomerang are too big, and the frequency of the balls is a bit too short. (DeepL from Japanese)
