The game was extremely fun and cool. One thing though. I'm not sure if it was intentional or not, but when I lose and restart the game, enemies from the last playthrough are still there. If this was intentional, I can see why it would be; but, my last playthrough was just me running away like crazy and gathering those blue thingies whenever they appear. As a result, the whole screen was filled with enemies, to the extent I suffered from slow-down issues. So when I died, and pressed "Play" to play again, my hexagon spawned inside the enemy and died immediately!
Other than that slight issue, I loved this game! I'm already a fan of "shapes fighting each other" games (I don't know if there's a name for the genre), and this was definitely one of the better ones! Controls were fluent, mechanics were cool (albeit a bit hard to understand), the music was enjoyable. I've also noticed the music slightly changes as my health changes. I think the pitch increases as my health decreases? Not sure. That was a cool addition. Very nice work!
