I already have played/own: Leo's Fortune Alex: Mayan Mysteries Bloo Kid 2 Last Inua - An Artic Adventure Lethal Lance Sonic ports Random Heroes He-Man: The Most Powerful Game in the Universe Blackmoor Ava's Quest HD Mikey Hooks & Mikey Shorts Shadow Blade One Tap Hero Prince of Persia games Apocalypse Max: Better Dead than Undead
Man, what a blast from the past. Sadly, I don't think it's available on the App Store any longer. A few that are: Wimp: who stole my pants Wacoon Jump Crazy Hedgy (if you want to try a 3D platformer) Castle of Illusion Nihilumbra Oscura
SuperCow Incredible Jack Terra Noctis Elemental Rage HD Cordy 2 Stealth Inc Shadow Blade Castle of Illusion
Kidd Tripp Miss Claire Garden Limbo Mutant Mudds Nihilumbra Type:Rider Penumbear Icycle Im actually quite surprised nobody mentioned Icycle.
League of evil 1, 2, and 3 (escpicially 2 & 3) Random heroes 1 & 2 Infestor LIMBO (already mentioned, but I second it)
I second Limbo and Robot Wants Kitty. You might also want to try Wimp: Who Stole my Pants. It certainly was great, but they've made it freemium and possibly ruined it. I haven't played it since they did that.
