Great stuff, very nice ambiance.
Level 6 is a great example of "show, don't tell", having an easy level to show you may need several light sources :)
That's quite a lot of levels for a 48h jam (plus, portals!)
The light beams look really good, how did you make those ?
The blocks kinda wobble around passively, which looks nice, but the hitboxes don't seem to update to reflect that, so it feels a bit Janky as Ian_W said. Didn't matter that much in the end with the current levels but if you worked on this more and had one where it's really packed it'd feel pretty bad.
