Thank you for playing and for the feedback.
Did you play in the browser or the windows download?
We noticed that the browser version has sometimes issues depending on which system-combination it is played.
e.g. on my laptops internal screen it works but on the external attached monitor the colliders don't work as expected. that seems to be a WebGL issue we cannot solve within unity right now.
We are also very dissatisfied with this situation.
Maybe you have the possibility to try it on another computer.
I hope there will be a possibility so you can still enjoy the game.
