Thanks for playing! I'm glad you enjoyed it!
Watching people work with the difficulty curve has been really interesting. Some people cottoned on really quickly, others took a while but still figured it out themselves in the end. I think there are ways I could communicate the mechanics better. That level with the four buttons, as you now know, is actually pretty simple. But the player only gets that once they understand exactly how the mechanic works, so that's what I think I need to work on.
I have no idea if I'll do a web build... that's new territory for me with GameMaker, but I know it would hugely increase my click-through rate...
