This one's very interesting! I think I can safely say this has been my favorite in terms of audio design & soundtrack: having periodic entries of ambient, droning synths is a great way to get around the limitation of short loops in Game Jams, especially in games where longer sessions are expected. Each track is very well composed and doesn't stick around long enough to get grating.
Control-wise, it's cumbersome, but it seemingly is intended to be something of a methodical game. Once a rhythm started to form with the flow of organizing and delivering, it became a bit faster, and the upgrades help in keeping your control feeling less and less clunky. I did feel like it was nearly impossible to ever get ahead in terms of the load zone being full. Having so many boxes spawn at once, especially before I had a handle on the controls, prevented me from ever catching up.
Aesthetic-wise, this is honestly great. It's super ominous, and I felt like it was hiding some secret from me. I could almost imagine it was going to be showing some hidden hand as to a larger setting or narrative it's trying to tell.
This is an excellent entry!
