Hey guys, There's a glitch that makes some levels unbeatable. Unfortunately it seems that sometimes a level will load in with one of the differences already solved, meaning that you can't use that difference to reduce the counter and you can't beat the level
two things. one: as a completionist, i find it annoying that it's not viable to max out every upgrade. two: the upgrade system is a little flawed, if you happen to get one much higher than the others, you have to kill yourself just trying to get enough xp to upgrade the others, this is why most games use the skill point system.
You are right =))
