This is one of my favorite games so far! Great art, solid design, and it's a 'complete' game!
My favorite build was leaf blowers + triple cast + strong seeking. I saved up all my leaf blowers for the start of the round, then used them to take down as many enemies as possible, then I'd mop up the rest. I beat it with this build.
My nitpick with the gameplay is that enemies have so, so much HP. It makes the first few rounds, when there's only a few enemies, seem like they take forever.
I would have liked different controls for SFX vs Music. I like the music, but some of the SFX, particularly the barking, is a bit too harsh.
