1) when I click on an object, no matter how obvious what I clicked is supposed to be, the obvious is stated. I.e. I clicked a big fat rock, and a message appears saying something stupid like "this is a rock". No kidding?
2) I can't re visit areas that I've already completed all the puzzles there in.
3) Terrible English grammar, spelling, and punctuation in a game made by someone who Lives in a country that has English as their first language, I. E. America, the UK, etc
4) Games that use "texting langue" in message popups and dialogs, I. E. LOL, OMG, WTF, WTH, FTW,
,
5) Games that use "geek language" such as Troll, Ninja'd, N00b, Pwnr, Flame wars, spammer, etc I think I made my point.
That's pretty much it I have more but they'd probably come a cross as too insulting for some of the members here plus I don't want to hurt feelings or stir up pointless trouble.
