Alright, I'll first say this: This game looks nice. The boss looks really cool too! however, I'm not sure if I have a clinical skill issue, or it actually is just hard. I think it was how I played it that caused me to find some strange oddities, such as bubbles popping if you somehow hitting them from the side, and (I think that) jumping off the bubbles higher with the spacebar really confuses me. The level design can be fun, but sometimes it can be a bit frustrating, and I think that the biggest issue is me not being able to do the bubble sections well :\
(which probs is just a skill issue lol) But, to returning to the more positive aspects, the controls are actually quite good! As well as that, the tying in to the theme is also well-executed! Overall, this game is quite cool, just for me, the bubble sections can be hard to do, and sometimes the controls become a lil floatier than usual. Good Job :)!
