Game will cheat you the more you play. You're better off just paying for a game that wants you to beat it, not one that wants you to have fun, then piss you off in cheap ways to try to get you to rage pay for stuff. Power up combos will get worse, things will hit you when they didn't, it'll randomly lag at that pivotal moment and kill you, not drop the item you need for months but constantly advertise a $2.99 special on the item you've been needing. Ultimately it's designed to screw you.
