The last level just stayed black with my little guy in the center. I hit alt and it finished the game, not sure if that actually did anything or if it was just a coincidence. Using Chrome and Windows 10.
There needs to be better controls. I can't seem to pause, sometimes the squares don't register, and there needs to be a restart button. Just to name a few suggestions.
I was having fun with this game until you made levels that required me to use gravity arrows and fans to move bombs across the room. Very rage inducing.
