I've been following some of your twitter posts and I was excited to actually play this one. It's a fun puzzle concept, and definitely a unique take on "movement" for sure! One thing I would recommend is making the players hitbox smaller if you can, squeezing into some gaps can get frustrating. Also, delineating between boxes that move up/down and left/right in code might be useful to prevent some glitches that you can come across. I also found that pushing a box into a forklift against a stationary box will push the forklift through the wall. Nothing game breaking, just some bugs I ran into. I really enjoyed this, good job!
Thanks for playing my game and hosting such a fun game jam! This was a great chance for me to dive more into developing with PICO-8 - which was a blast. I really appreciate your feedback - spot on. When I get time, I hope to continue working on this game. It was a lot of fun to tinker with, and I'd love to release a v2.0... some day. LOL! Please host another game jam in the future. I'd love to participate again.
