1: Ah, well, simply speaking, when you put bullet hells into 3d, they become unplayable garbage. It was a genre made around single dimensional gameplay, with single dimensional bullets, and it just adapts real bad.
2: My apologies! I’ll provide an optional theme for ya guys who want one!
In my opinion, games like Nier series or Returnal are pretty good examples of bullet hell working well in three dimensions.
Also, what if game is made with 3D technology (as in, 3D models instead of sprites), but still works like 2D bullet hell (as example, some bosses in Furi)?
i don’t think 3d is a good view on such. With your 2.5d ,then that’s fine. The spirit of the jam, more or less, is the danmaku element, not so much the “just dodge lmao” element. If it isn’t top down or flat, then it truly cant embrace it in the same way.
