Out now? Wow, I need to download it.
I tried the demo for the backers a few days ago (just played half an hour or so) and it's a pretty good beat'em up. It feels a bit stiff and the characters don't seem to have combo strings; in other words, pressing the same attack button will repeat the same move over and over, while most beat'em ups have some sort of autocombo when you keep pressing the same button. There's a combo system, though, and the characters have special moves and even a dedicated meter for them. I'm not sure how it works, but it's nice to have. You also have a block button and you can pick up items and even enemies from the ground. Of course one of the items is a frying pan full of beans!
Also, pixel art is gorgeous and I love the little dialogues between the characters that emulate the style of their movies.
It looks like a decent game by itself, but the license is what really sells it. If you like Bud&Terence, you'll love this game.
