Woop Woop Warpo!!
Ok, Im not going to delve on whats already been said, the parallel process kills your game completely and I also got the fatal crash of .lastskill. fortunately, I got it on the second fight so I restart the game. Another thing is. If you restart the game and press the ok button fast enough, the picture of "Warp enegma presents" will never go away. So I had to restart again.
I like the core mechanic of having a timer, that coupled with the music really felt pressing in a good way. I liked your dungeon design as well, giving some different paths to your player. I was able to beat the second boss but then , since i was super lagged I walked into some damn spikes and died =(.
So, I think this if polished, would be something real good. I good idea is to let some close friends play it before uploading the jam, that way you can get those pesky obvious bugs out of the way real quick.
