I applied the fast cheat
After that the game got really buggy. Sometimes the piranha wouldn't register the position of my cursor and just get stuck and my small fleet of two keep disappearing and reappearing. In addition sometimes level 3 can be buggy all on its own. the objective is to kill 3 people but sometimes no people will spawn into the level: no boat, no divers period.
The idea seems fun but there are a few kinks to investigate and fix.
I would also suggest there be a way to turn off a cheat in case a player doesn't like it after all.
