Hi Ethanol, I am so sorry you ran into all this mess :p .
Thank you so much for detailing these bugs, I've forwarded them to the team. That massive white UI box and the wild 45-degree camera tilt are definitely high on our fix list. We're also removing the melee feature :D
We are a tiny team and still ironing out the Early Access jank, but fixing these critical issues is our top priority for the next hotfix. Thanks for your patience and for helping us catch these!
