There are definitely game-breaking graphical glitches in Chrome and Firefox in Windows for me. Another game I played that was made with Construct had the same problem. (If not everyone is seeing them, maybe it's video card dependent?)
That said, the graphics I did see looked really cool. The hand is nice, the fire is gorgeous, and it all fits together nice. The sound is also good. There's some talent here; I hope you can use a different engine for next time.
