Very consistent art style and clean and easy to use UI. I especially liked how I was allowed to pause the game to rearrange my loop queue! The player choices are nice and simple, the difficulty curves up nicely (I won!), and the game overall seems like a nice and polished!
I noticed a few stutters that seemed similar to a problem I was having with a Godot web export. It might be related to spawning individual particle emitters for the first time, and rendering them all in advance could help get the stutters out of the way up front.
Great game, really impressive!
