I hope I don’t seem to rude to you but in my opinion:
The game is just too plain or ugly, you should change the colors more pastel and the kill parts make them less brighter, you could barely see where to step at due to their brightness.
The obby is too easy to complete, you should add a higher variety of stages and less just jumping-only.
There are bugs with the stages, first time I joined I was in the Winners team for no reason, when I rejoined I spawned in Stage 3 and everytime I kept dying I went 1 stage ahead.
I have the same issue with my obby. The teleporting to another game. That is because you have some type of free model made by another person. Keep up the good work bud.
