It's been a long time since I played a decent beat'em'up. This one being a LD48 entry makes it double impresssive!
There's not much to say about it. The whole gameplay mechanic is directly pulled from the dime-a-dozen beat'em'ups from the early 90s (like Capcom's Final Fight): walk around, punch everything that moves, punch everything that doesn't move for extra bonus, pick up stuff to throw at everything that moves, health bars on top of the villeins (which of course have silly names), and so on. All this just because the poor protagonist was denied of his raise. Sad isn't it :)? Graphics and sounds are quite top notch and the game plays quite good (like I mentioned).
