Vonneguts & Glory is a free game that’s soon to be released on iOS. It’s undergoing the approval process, but should be available so long as Apple gives it the okay.
It’s an interesting little title, and you can check out the browser version here. It’s pixelated and old-school, but that just adds to the charm. The controls feel a bit awkward, but it’s fun to check out something that feels so retro.
