Tough but incredibly satisfying. I love how precise yet chaotic it feels, especially as things ramp up. There's also a lot on offer, each level having its own unique mechanic. The only real criticism I have is that there aren't a few easier levels to cut your teeth on; all the current levels feel like mid to end game challenges. I could easily see this expanded on with a progression of levels introducing new mechanics and expanding the arena a little at a time. Overall, a small but fantastic game.
