- Ynth (Amazing action puzzle, Beyond Ynth recent release made me discover the original, Beyond is perhaps a better choice but I haven't yet played it)
- Knights of the Phantom Castle (Difficult but great, a sort of Syndicate with a Fantasy background, and not exactly the same budget level)
- Spirit HD (Great action game, learning curve is a bit rude)
- Somersault (Great original platform game)
- Orions: Legends of Wizard (Great Strategy RPG Card game)
- Block Breaker Deluxe 2 (The best brick breaker)
- R Type (Oldie shmup but great, a bit too difficult but worth the sweat)
- Despicable Me: Minion Mania HD (Great puzzle platform game)
- Knight Defense HD (Original and very fun mix of TD, action and strategy)
- Stranded Mysteries of Time & Dracula the Path of the Dragon HD (Two very good adventure games for different reason and different genres)
I don't have a slew of games yet, so thanks for the suggestions. I've found a few websites and the FreeAppADay app that tell you what particular apps are free that day and that has led to me finding a few gems.
Below are a few that I've come to really enjoy.
The Treasures of Montezuma
If you like Bejeweled matching games, just get this now. I can't stop playing.
Galaxy on Fire
Reminiscent of the Wing Commander games from the 90's.
It's like Asteroids with a tilt.
Beautiful Zombie defense game (not like TD)
Virtual Table Tennis
It's an iPod game, but plays well on the iPad. Very addictive.
It's effing Air Hockey!
Has a lot of two player board games
