Yowza, this is some great stuff! Reminds me a lot of other fast-paced action puzzlers like Dandara, Ghostrunner and Scourgebringer, and just like them, I very much enjoyed finding the best route to slice and dice through all the enemies in a stylish manner. For a game jam game, I'm very impressed with the presentation quality: the transitions and slow-mo were very slick, and a special shout-out to the very stylish title screen which makes a damn good first impression! The boss fight at the end was a great cherry on top of this sundae: well done!
While I was able to make it through the game without much issue, there were a few aspects I wanted to point out:
*Some aspects could've been made a bit more obvious in how they worked, such as the launchers and how they have a teeny-tiny colored pixel on them that indicates how much power you'll get by going into them: I didn't notice this for a long time!
*The whole color tier system was weird and difficult to nail down. For example, it was annoying in how you start with an orange bar, and yet you're not really orange because you'll immediately go into the white tier once you start (hope you didn't immediately launch at an orange enemy!) I also wish the HUD bar would have the sections lightly colored even when not filled so you could always remember the order of colors as it increases. The difference between the red-orange breakable tiles and the red ones were too close to each other that it could confuse me as well.
*It's a small nitpick, but I wish the exit would open immediately upon killing the last enemy instead of waiting until your next dash following the kill: the weird delay can make me think I still have enemies remaining when I don't.
*Another small nitpick: I wish the game would let me click on the window to focus without immediately selecting an option on the title screen. Also, I wish the game would lock the cursor within it so I can't accidently click outside the game.
All in all, though, as long as you just believed in the game and moved as best as it seemed intended, it worked out, so it's not that big of an issue!
