My first game (after Pong) with Impact. Anyone have an idea why it doesn't work on Firefox and Safari? There is an invicible wall preventing the guy from progressing in those browsers.

Just 2 levels right now, you have "won" if you get to the second exit.

I noticed that the player does the weird "vibrating" animation in your game. He occasionally did that for me when I did the HTML5 Game programming book tutorial as well. I wonder if anyone knows a reason why that happens.

I&039;ve seen that happen in my games when the position of my entities or the camera don't align on pixel boundaries. Are you getting real numbers for position instead of integers? Try rounding your positions with #Math.floor.

Where should I do this position rounding? I am a bit lost. There seems to be invisible collision wall in front of the player. No entity passes through. One can simply walk a little bit and jump.

Love the music!
