Wow Aqua globs is hard! It's confusing with what has to go where :/ i'll give it a few more goes but it's not looking... hmm...
Aqua Globs is fun, for sure but not very repayable, for me at least. I ended up putting it down after about 10 or fifteen minutes. I wanna try that scissors game! If you already have Labyrinth 2 why did you start this thread? It IS the best game! Try making your own levels! Try my levels too! My ID is in my signature! If you have made your own levels what is your ID so that I can try them?
Since you're in the UK, how about Cricket Game? The in-app bowling purchase is a must have - altogether US$2 for a really good distraction. If you hate cricket , I'd second the recommendations to have a look at Soosiz .
Red Conquest, while there's so many new games out there that's the one I'm recommending (and wow has it got a lot of recommendations in this thread). Basically what others have said, an RTS suited for the touch screen, rich gameplay, tons of fun and with the upcoming online multiplayer it can only get better. And it's already way better than any other iDevice RTS in my opinion, Warfare Inc comes close but it falls back with the little things, like units not attacking on site. It does have a ton of downloadable missions and pretty clean multiplayer. If not Red Conquest, then I'd say Goals! I've played so many matches during class..
I just tried Aqua Globs Lite and while I can see how people enjoy it, I just don't like that kind of game. If I had to recommend one game right now, get Minisquadron.
