I downloaded the game yesterday and played it for a bit. I'm pretty sure I've played this before on MAME. It's a really well-done port of a pretty shit game. I don't care for it, at least. It's an isometric adventure game, with a Dungeons & Dragons arcade vibe, but it's just not very fun. And the sound effects are garbage.
The intro screen is hilarious, though. It's got the Johnny Turbo logo and (I assume) Brandsetter's voice saying, "Johnny Turbo Presents..." From there, they've got lots of settings (RGB, HD, S-Video, Composite, 4:3, Stretch, etc.), which is nice to see. It's a two-player game, and you can select one of four characters.
The game is alright, I guess. It just didn't feel right to me.
