Really interesting concept! I liked how each character had different traits that you needed to figure out. The sound effects were a really nice touch. Having only one character with a light was a bit hard to get used to, but I understand the decision.
The hitboxes on the characters were a bit rough, as I sometimes had to wait almost a minute in order to get back to one character to move him slightly. But besides all that, it was a pretty enjoyable experience :)
Nice job!
