Well, 1 programming the ai for a shared wheel was spotty at best, and with more complex items it made it even more difficult to balance. Also i think the game is at its most fun when its more of a "rube goldberg machine" of items interacting with each other, and having potential enemy slots complicates builds I think. For example, boomerang is a much more interesting item when all slots are yours since you know it will at least hit something beneficial. Basically just a way to reduce some of the RNG. There is already the "spinning the wheel" which is a major RNG focus, so ive just been trying to reduce the amount of randomness as much as possible. Also having enemies telegraph singular attacks/moves allows you to strategize what items you want on the wheel better. Haha.
Sorry for the novel, just my thinking. Haha. Basically think slay the spire, but instead cards you get items and the whole wheel to yourself instead.
