Out of curiosity, were you playing in a browser while testing?

Yes, I tested it in a browser as well.
Though that may be the key to the problem, that my dev machine has a lot of RAM and a pretty powerful GPU. (Not that this game is very graphics intensive.)
I will test it with a less powerful machine, though I'm not sure I will change something if it's just the browser build, that slows down.
If the downloadable version also slows down I should look into that.
Thanks again for your feedback.
Oh, and I forgot to mention in my previous reply: Despite everything, good job getting to Level 47! That's not easy even with properly working controls.
