Thanks! I'm glad you liked the game. I was very worried about properly explaining the mechanics, I added a bunch of tips but I fear they're still not super clear haha.
Regarding the fast-forward mechanic, I'll probably upload a patch with it either today or tomorrow. The actual reason why I didn't include it is that my code was pretty crappy and I feared it could break lots of things without some proper testing (and I didn't want to rush it).
