Honestly, my only complaint is the playground level. I get that there are mutiple paths, but after I got a ways in, I had no clue how to progress from there. I tried a few different things, but none of them worked very well. I'd suggest some type of optional guidance system, that shows you one possible path to do the level. Since it would be optional, it should show the easiest path to do.
That is pretty much it.
Some maps were (and will be) reworked before the final release. Playground is one of them. (It's the one map were i somewhat neglected one of the core mapdesign principles compared to the other maps.)
Great to hear that you had that much fun with the game. Can't wait to finally release the final product. :)
