Did you get World of Goo? It's frickin weird but cool.
I picked it up back when it was on sale for $1. Ended up deleting it out of frustration
I can't quite remember exactly why, but it had something to do with too hard of achievements or multiple tiers of goo saving goals, and the toughest tier was too difficult for me to complete on the later levels or something. Not being able to get perfect on the levels caused me to commit the ultimate rage quit and delete it altogether haha
Edit: Ah yes, after searching, it was the OCD level challenges that did me in. Oh no, now I'm contemplating installing it again.
