1. Isn't Epic Games or steam a publisher?
2. I had a bug where I couldn't move, and another one where I couldn't jump until I died
1. Unfortunately no, they only publish games on their platform. A publisher is a company that sponsors the production of a game and promotes it. It helps you release the full game. ;) Theoretically we could try Kickstarter, but we're not sure we have that kind of reach yet (well, and it's a lot of work!).
2. We want release next hotfix soon. If you want to help us, please join our DISCORD. The rules for reporting bugs are already described there. :)
