The rest of day 8 and day 9:
I've refactored code and fixed every bug I managed to find. Platforms moving up still work a little funny (you "jump" at the top end of pattern), but I think that it's not that bad. I've changed level, so now it's longer. There is also first sound in the game. Currently it's switch sound, but it's going to be more soon.
Tomorrow (Well, actually today since it's past 00:00) I want to finish level using placeholder assets. Next 3 days I'll be working to make some assets so people don't have to guess that cloud is really a switch. On last day(s) I'll just make some finishing touches.
