I really liked this game (and I'm not really into that type of game), but I could see something genuine and identity. For me this is a game already in beta and can easily find your audience. Please continue the project. For me there is only something in the gameplay that is bothering me that I can not say for sure what it is. I do not think you need the space key to get the power ups. It would leave without this necessity to be able to leave the game more fluid. Getting stopped squeezing and picking up power is not cool. Maybe push to activate or use when the player wants, so would invest in an inventory. The music is perfect. I got to understand what you did with the theme, but boss rush follows almost as a "genre" game, but you did a good read. Well, that's it! If you can, vote for me too. It's BossMoji.
