during the fist fight i pushed the guy outside the screen and even after reloading the game and going back to redo it he now spawns off screen and doesn't come back so you cant beat him once he goes off screen.
the flashing part almost gave me a seizure while playing please mark your game with a warning so people know i had to stop playing at risk of my own health so please add a warning to the description.
Found a exploit where saving and returning to main menu will reset the upgrade cost allowing you to rebuy it for its original cost with out losing the upgrade to clicks like buying the 500 save then return to main menu and load game the upgrade will go back to only being 500 but you will keep the +3 allowing to get +3 again. Other then that its a nice clicker good for passing time at work or away from home.
