New game from one half of Team Meat who obviously made Super Meat Boy.
A different type of game but with a similar art style.
To me i've been playing it and i've gotten vibes from it similar to Legend of Zelda, Bomberman and Metroid.
Basically it's a sort of top-down shooter where you control a kid called Isaac who i guess is trying to escape from the basement under his house. It must be emphasized that every playthrough of this game is different.
The rooms are randomly generated and the monsters within the rooms are randomly selected. On each floor you then fight a boss.
I haven't gotten too far yet but it's a short game, but with lots of replay value. If you die once though you have to restart the whole game.
It has an interface similar to LoZ and Super Metroid. You use wasd to move and directional keys to shoot in the corresponding direction.
Basically if you watch the video it explains all better than i can in text.
NOTE: it's pretty gory so the video may not be safe for work. It's a "cartoon gore" artistic style and has a pretty down-beat soundtrack - at least in comparison to Super Meat Boys!
