Wow, the particles and effects in this game are so cool, I loved how unique every character's abilities are. The game looks really interesting and aesthetically pleasing.
A few suggestions: most times I didn't really get what killed me. It would've been nice to have more visual feedback from hits and more time before showing the "death screen." (It's funny for me to comment on that considering that my game has the same mistake). Also, I wasn't sure what some of the characters do. Maybe some tutorials might help? And finally, I think one life doesn't feel right. I want to play more, but the game forces me to stop. Give the player more chances (actually one more, it's the same as with my game: use keyboard to restart the game, not the mouse!)
But overall, I was engaged with the game, I really had a lot of fun with it
