Game development is fucking hard dude. 0.9b is a test build anyways, hence the word "TEST" in all caps, 3 times. Shit will be broken, it WILL snap you out of bounds, things WILL NOT WORK. it is stressful, it's time consuming, and it is NEVER pretty. reiterating what I said earlier, 0.9b is a TEST build. it's not meant to be pretty and playable by the average person. If something broke, it needs to be fixed, things that worked in earlier builds may not work in newer builds, that's the joy and frustration of development. these builds are meant to FIND those broken things.
