Path of Achra
Path of Achra is an extremely good time. It lands somewhere in the middle of traditional roguelikes, overpowered-build-making ARPGs in the Diablo sense, and idle games, and while it's very straightforward, this means there isn't much between you and the numbers that go up. It's a game you can beat by building out a character who only ever has to wait in place, and that knows you can do that and gives you two dozen ways of doing it. Or, to give a more specific example, in one successful run my character was fully nude from beginning to end.
The writing's also good, if you're into paintings on the sides of vans-type fantasy. While mostly limited to item descriptions and assorted flavor text, the dev clearly cared about that part of it, which is nice to see.
