Hohokum
Hohokum is a journey into the unknown. If you've already accepted this then go ahead already. And make sure to turn the light out and remove the battery from your cell phonet.
I bought Hohokum twice. Once on PS3 and again on PS4. I never found everything, though I think I came pretty close the first time. Some of the areas remind me a bit of Electroplankton. The soundtrack is an incredibly solid mix by various different artists including Tycho, Com Truise, Michna, Joel Corelitz, and many more.
The entire experience is whimsical and playful. I hope you get to experience it too.
