Hello! I’m the programmer. Making a multiplayer game in under a day wasn’t easy. 30 minutes before the deadline we decided the game ended too soon so we added bouncing to the borders. If the coffin hits a border 15 times, the game ends. We didn’t have time to add a health bar or something that actually made that clear. Sorry!
The cursor thing is because it’s actually a mobile game and that’s how you move in Android. Also 30 minutes before the deadline, I mentioned the game should work cross-platform and someone said “build for Windows too!”. It works on Windows, but you can’t move using WASD/arrows controls, so you get the Android d-pad lol
