Since many people observed that the boss in our game was actually crashing the game when running in HTML5 mode, we have released a bugfix release clearing up this and several other major bugs. Now all 16 levels that we had included should be accessible (later levels are quite difficult but possible). Give it a try if you haven't yet, or if you made it to the boss but couldn't progress due to the crash. Thanks for playing!
