awesome! The guide was funny as hell (you are not a crate lol), and i loved the retro feel without retro glitches. I did notice tho, that there were a couple of issues.
Level 10 seemed to be a bit broken unless i just completely misunderstood the puzzle there. I spent about 10 mins on it before assuming that the crate was supposed to push the button (it did not), because there would be no other way to reach the exit without having to jump on top of the bomb (of course, resulting in death)
other than this, the only issue i have found so far was in the platforming on level 7. It seemed like i just didn't have enough space to get up those ledges in less than 10-12 tries, and i'm not sure this was supposed to be so frustrating.
great game!
