Wow, thank you for all the super-nice comments!
@Jan Marcano, @nek: Thanks! Do you think that some sort of reminder bar which lists the combinations would be useful?
@LittleThor: Glad that you loved the love thing and the music! What don't you understand about the beginning?
@Sergey Mohov: Do you know what level that happened in? Glad you enjoyed it! And thank you for noticing the level editor! I think that it's the best bit of the game! (I said totally unbiasedly) :P
@Morgawr: Well that was lucky, managing to mash 'em until you got it right :)
And yes, LINUX POWER!! *explosion sound with guitar solo*
@doonay21: OK, I'll add an option to the post-compo version to let you choose if it does that.
@jhelle,@josefnpat: Thank you both for your super nice comments! I've found that I missed an "if not tiles[x][y] == nil then", which is causing the error. I'll fix it after the compo, but for now it is easily avoidable by not mashing the keys :P
@motty: Have you tried compiling the LOVE 8.0 source code? That may work. Anyway, glad to hear that you enjoyed it!
