Tried this on Firefox and Chrome but unfortunately it seemed to lag for me on both (very bad lag spikes), so I couldn't really play or rate the game, sorry!

edit: I'll download the Windows version and give it a go

edit 2: Ok the Windows version also didn't work - I got errors trying to load it (extracted the "Windows copy" folder and ran the exe, pck file was present so not sure why it's failing to load the resources)

Browser resolution didn't seem to work correctly

Very satisfying, for the better or the worst, I could not die and ended up with -1500hp. I also had some issue with the camera but still had fun. Good job!
