The LG 800 G phone comes with:

Container Block
Castle Defense
(sorry, no downloads on these cause they're built into the phone)

Here's what I've got working so far:

Angry Birds
Bejeweled
Crystal Defenders
Final Fantasy (touchscreen)
Final Fantasy II (touchscreen)
Fruit Ninja
Tetris Revolution
The Oregon Trail (it sucks)

These games load but don't play very well probably because the phone is too slow:

Bejeweled Twist (can't get through the menus, probably because phone too slow)
DJ Hero Mobile (everything loads fine but game seems choppy and slow)
MeBoy (emulator, framerate is less than one frame per second even on original gameboy titles therefore unplayable)
Minecraft 2D (great idea! wish I could find the original author, but runs annoyingly slow)

Also:

Assasin's Creed (haven't tested much yet but it loads)
Tron Legacy (Can't find touchscreen 240x320 in English - help!!)

I can provide downloads of any of these on request. But I'm more interested to know if anybody knows of any other 240x320 touchscreen games I should try?
