Holy shit. I love this game.
I adore the soundtrack choices so much, real tracker module flavour. Sound design is also great. The visual style reminds me a bit of whatever aesthetic they were tapping into for Invader Zim, and I love the icons on the blocks telling you what you need to do to clear them (although I was a bit confused by the cyan face blocks). Simple concept executed with great polish. I liked the interactions between captive and captor, too.
