I am loving this game, but I could really use a walkthrough... this gets really challenging!
Yeah, it's tough! Maybe I could introduce an in-game hint system. Need to think about it a bit. I have a day job so I can't dedicate all my time to this game and it takes a while to write good hints.
In terms of getting stuck, if you've given it a good shot I would suggest skipping ahead. Maybe something in a later level will trigger some understand that will help you with the previous one.
