Hey thanks for playing, yeah the reason it's a UE4 game is because I'm more knowledgeable in regards to it compared to other engines like unity or other ways to develop games. I do agree that a web game or light weight game would be easier but again, I don't know how to do so. Thanks for pointing out the back ground issue, should be fixed now. Interesting, I've play tested my compiled game many times and it never bugged after the beating the boss, but thanks for pointing out that as a potential bug.
