It's awesome, it runs well and I don't have fps issues, sometimes the animation lags out though like a glitch going back in time for a second. The first boss spider bat thing... I ragequited there because I was out of range and he still could hit me. i'm not sure what's up with that boss, but it's almost impossible. I was one hit left and he killed me xD Once that's fixed I'll try again. Or maybe tomorrow i'll try again when i'm actually not tired :) for now it's not for the casuals :P I demand a normal difficulty xD Once it's a bit better, i'll continue to do the video.
Edit: I killed the first 'boss' turns out it's not a boss at all just a special minion. But after playing I found out I have to go against two of them?! There I stopped again xD It's insane, but you can kite them though. I had the kind of lag out the whole game and I will post the video as soon as possible. Sometimes when I rolled behind a mob, he could still hit me. Also a checkpoint after the first special minion would be nice, because even though I had to go through the door... there was no checkpoint.
