I originally rated this all 0 because I was clicking the start button and nothing was happening, so I assumed it was broken. Then I pressed the space bar. I still couldn't figure it out until I read the other comment, then it all made sense. It's really good! I absolutely love the chiptune music and the sfx are great! The 2nd level, with the ... things...? coming towards you is done really well, except that they pretty much never come on the right side of the screen, so you can mostly just stay there and hold space. On the bubble boss level, I got knocked off screen by a pillar, and it glitched the game out, forcing me to restart from the beginning. I wish there was feedback when getting hit in the 2nd level. I also wish there was more!
