Like Asdonaur said, it's a bit harsh to start over again for just one hit. Maybe if the animation of Ctl+Alr+Redo was a little faster, it will give more agility to the game play feel.
Also, it has some sort of bug where the players doesn't spawn at the start of the level, and you have to reload the game again.
The chat box where the AI talks and produces the cheats is so much fun haha
The concept is overall very nice! Congrats!
