Cute little game, I liked the simple puzzles! I think with some more concretely defined systems (gravity, maybe environmental hazards) and tighter movement controls, you could make a genuinely enjoyable physics puzzler.
The split system of movement, with red moving on WASD and yellow with the mouse, isn't the easiest to pick up, but again, I think it has some potential for more complex and exciting interplay. I definitely had some trouble with both in their current state (red's frustratingly floaty and the tether puzzles were sometimes just luck for me) but that's not a knock on the core idea.
When I first heard the event theme this was exactly the kind of mechanic I was imagining, and you executed on it solidly! Nice work
