The art was nice, the little bits of humor (such as being an orange in another universe) were nice. The gameplay itself was good and I enjoyed that there were unique mechanics for each different person, I particularly thought that Faun's was cool. That said, there wasn't much of a story or anything but it kinda seemed intentionally surreal in that way as far as I could tell (and what do I know)
Admittedly I didn't realize that all of them required different numbers for automation... I got Faun up to e80 before I happened to check the tab and see I only needed e35 lol, oops. Also some way to change between them other than clicking the labels would be nice, so I could continue systematically swapping between each & buying upgrades without moving my mouse too much
Some kind of SFX or music would be good, definitely seems like the kind of game that would benefit a lot from cool music given that the art clearly had a lot of care put into it too
