The best entry into the Metal Man franchise by far! Can't wait for Metal Man 4 - Meat Over Magnet!
In all seriousness, this is a fantastic submission to the jam - probably one of the best and highly likely to win! So creative, funny and an amazing product for a 4 day jam. You seem to work really well as a small studio, please keep making games!
I did have some performance issues on web when compiling particles for the first time, something I have experienced before in my own Godot games. For web builds, I'd suggest triggering these particles in the scene offscreen to get them compiled into memory. Other than that, flawless!
