So this is what happened to the monitor I ordered from Amazon...
In all seriousness, this is great, haha
I haven't been able to fully finish any of the sub-worlds yet (the last few puzzles of each one are t o u g h), but I have gotten the credits - And this is a nice variation on the usual mechanics! I dunno what mechanic I like the most. Everything is cool in their own ways, and the exploration of the mechanics seems to be really thorough.
(Also in-edit, the music slaps and fits the tone some of the mechanics seem to imply)
I do like this game personally, but I think the lack of keyboard compatibility is very alienating, even if 3rd-party controllers these days don't go for very high prices. I did see the dev's comment about how the game felt "terrible" to play on keyboard, but I still think the option to play with a keyboard OR controller would be nice.
