I think it needs more fine tuning in terms of movement and keybinds (maybe left click and right click for the knife) and finally, the knife is taking a very long time to travel... Apart from that, cool game!
Yeah that was quite the problem we faced during the development. In the end we settled for Q and E as Scratch would not allow us to differentiate between "Mouse Left Click" and "Mouse Right Click". In the end we were just happy, that we got the procedural generation working lol
