Thank you for playing and commenting. The browser version is the same as the windows doenload version.
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.
