Played quite a bit of Tiger Road the other day. Really fun, but kinda frustrating game. I'm not a big fan of the weapons, as some of them don't seem very effective, and there seem to be quite a few cheap shots from the enemies. For example, there's a level early on with a moving platform that's just off screen. When you jump to it - BAM! - the screen scrolls and an enemy hits you.
I don't know that I'd have the patience to try to finish this one.
