Christmas has come and gone, and I'm now the proud owner of a 4th generation iPod Touch. As far as games go, the ones I've downloaded are mostly freebies. Only two were paid for.
The first was Doodle Jump, bought to be used as a time waster app. It is very addictive, perhaps because its sheer simplicity is such that you always feel you could have done better. There's not exactly a tonne to be said about it, though.
The other title is one of the more highly received iOS games - Spider: The Secret of Bryce Manor. This is a 2D platformer with light exploration where you control an extraordinarily agile spider as it explores an abandoned mansion. There's a minor story behind the mysterious setting, but it's worked into the environmental features and is mostly unobtrusive. Where the game truly shines is in its primary game mechanic, which is to hunt bugs by capturing them in your webs. This generally controls well, better than I expected, and due to the various score multipliers emphasised in the tutorials, the plotting of your spider's web lines becomes quite strategic. It will be interesting to see how that develops. Lastly, the quality of the soundtrack took me completely by surprise. It was on sale for 59p when I purchased it, though I don't know if that sale is still going on. (Edit: Just checked and the sale is still on for a limited time. I can only assume that it's 99 cents in the US.)
I'll review this thread for recommendations later. Preferably, I want to avoid games with fake D-Pads or joysticks, as their reliability is apparently questionable.
