Very simple game, but fun. I like the visuals and sounds. I was a bit confused at first what the turrets and buttons did but it didn't take long to figure it out. There's also a bug where some tiles don't light up when you can place turrets.

I like this track's arrangement a lot. i think it builds nicely into the more intense sections. I might have considered breaking up whatever synth/sound is making that high frequency white(ish) noise, as it might have emphasized the rhythm more.

I also use an m audio keystation for midi, but it's an older 88 key model lol
