It's awesome man. I found 2 bugs. The first I've already PM'd you about. The second one I'll just post here as it's less complex. I was using the z and / keys to control the flippers. As you already know, sometimes when using those keys the ball will slip past the end of the flipper. Well, on my first ball, that happened. After it did, a new ball appeared in the chute but pulling back on the plunger no longer worked. It may be worth noting that upon releasing the down arrow, the sound effect still played, but nothing else happened. I was able to reproduce this once but only in full screen mode. It happened in Chrome, I didn't test in FireFox.
Edit: I used the space bar to bump the table and nothing happened. I bumped again until it tileted and the ball shot up the chute very fast, but it didn't leave the chute, it dropped back down. I tried the plunger again and it still didn't function. Now I am able to bump an unlimited number of times without tilting, the ball is still in the chute and the plunger still doesn't work. Also the game over text never appeared.
