I have just recently gotten the Launch ability and the physics and effects are cool and fun to throw things at enemies for sure, but I'm also perplexed by the strange design choices they give you shortly after you obtain this ability. You'd think for the first boss fight after you obtain this ability you would need to use it on the boss in some way but nope. Boss just quickly moves out of the way if you throw anything at him so you're forced to just use your pea shooter on him again. So strange and odd design that takes the fun out of what would otherwise be a thrilling boss to fight of using a mixture of launch and shooting attacks.
This is the exact point at which I stepped away from the game for a while. That fight is some 1999-ass design and it's not interesting. Unlike the OP, though, I really have enjoyed the world (I did eventually go back and get to the motel a little bit after that) but I think it's going to sit until I get through some games that didn't turn me off so hard.
