I think this is the hardest entry I've played yet.. and tbh it's not that rewarding. I get the whole propel yourself mechanic.. but idk. Cool graphics and art though. If I had to guess, my feedback is the propel mechanic should be a lot more "responsive", both physically and effects. I actually tried it before reading the comments and game page and didn't think it was possible, I didn't even notice it was happening is my point.
