It gets out of hand really fast, the difficulty balance was VERY last-minute (you should have played the initial version, I never finished 2 loops). At the moment there is no "end", you just go until you die. A fully-fleshed out version would have more levelling for sure.
We made 3D because, well, we don't know how to make 2D hahahaha. We are VR people.
Thank you for playing a a thought-out comment!!
