Blake's Adventure is a fun adventure game for one or two players. There are four worlds and sixteen different levels.
Awesome! Graphics may be simple but it's a nice style and overall the game is very enjoyable and well structured. I liked it a lot!
I only found one issue with the boulders in the cave world: one of them hit me straight in the head and pinned me down without killing me, so I had to restart the game because I couldn't move. You may want to fix that. :)
