Thanks a lot for playing the game :)
No wonder you never heard about ObEngine hehe, it's a engine I've been working on for ~5 years but it doesn't have a stable public release even though the source is available at https://github.com/Sygmei/ObEngine
Game jams are perfect for making new features / improvement to the engine !
About the glitch, yeah I'm aware of it, I'll try to fix it :(
