If you enjoy LSD – Dream Emulator, that is, then take a look at Infinite Sunshine Dust. The game was inspired by Osamu Sato’s LSD and brings with it similar exploratory gameplay.
It also seems to have a dose of Yume Nikki with its top down perspective and dose of anime nightmare visuals. The default gameplay mode is an infinite mode, though there is apparently a story mode as well. Right now
Infinite Sunshine Dust is in Early Access and expects to remain that way for about six months. Infinite Sunshine Dust is available for $11.99 on Steam.
