A few games make their whole point in levels that are easy to figure out but hard to pull off. VVVVVV, Super Meat Boy and the Bit.Trip games fall squarely into this category, for example. You're basically expected to put in the obviously correct sequence of button presses and depresses at the right time; that's "all" there is to it. For whatever reason, this is a category of games that is having quite the draw on me as of late.
This however results in pretty hostile game design where there is very little room for error and plenty of triangular spikes with square hitboxes.
Certainly, pulling this off by yourself takes time, focus, determination, reflexes, muscle memory, skill and is very rewarding when you finally do beat the fucking pong boss and collect that trinket just out of reach. Sometimes, however, it dawns on you that perhaps one challenge isn't just worth it in the greater scheme of things.
For those times where you want to give up, cheat yourself and move along.
Is there any software able to record and replay keyboard and mouse input for games?** I'm afraid general-purpose tools like AHK wouldn't be able to do so with the required precision (relying on system
sleep()s isn't reliable for example, while running on each frame sounds like a better idea.)
