Luckily, the build worked for me! I feel like the controls are the sticking point for others, quite literally. I had to use keyboard and WASD and it worked alright for me. You may have to jump a few times to unstick yourself to be able to move. It takes a sec to figure out. I think having the controls listed somewhere would be a big help in this area. I wasn't able to play with anyone else, but the single player still plenty interesting! It was one of those things where I felt like I had it down after level 2 or so, so I started trying to see how I could cheese things just for fun. In the level with the two scrolling vertical rectangles i found a way to gain momentum on the starting platform and was able to get a huge running start to the wall on the other side, which felt really cool. I think I ended up brute forcing most of the levels, just cause i found a lot of fun in just winging the solution. I also felt like there were some jumps that i just couldn't make without cheesing it, but that's probably because I'm a little tiny dumb smelly baby who got impatient.
Anyway, would love to try this out with someone sometime to see what that experience is like. seems like it would be fun with a friend. I'd love to see even more with this concept!
