The character flies off the platform at the Z coordinate VERY often. That is, if you crash into the platform, you fly off. If you crash into the prism (which is at the bottom of the spawn and near the stairs, it is located directly on the path, not on the side, like other prisms) - you fly out. If you get in and get off the ladder - the character is slightly shifted by Z, because of which the player's trigger no longer reaches the levers or ladders. Very annoying. The player should be fixed on Z coordinate or change the collision to square. And after activating three prisms nothing happens, the door does not open. Perhaps because I can not reach the door without moving on Z (If I do not fall off the platform when moving on Z, then the levers and ladders stop responding to press E. The player's trigger does not reach them. Probably the same with the door).
On pause the game forgets to show the cursor back, so the restart and menu buttons are useless - they just can't be pressed, because there is no cursor.
