Nice work! The dogs are a little bit too hard to fight; I don't get how to defeat them without getting hit. The roll you do to avoid shots should speed you up for a moment—it would make it more immersive.
On the sea map, it's a little bit confusing that I have to press up to go left (level 2).
Also, it's strange that you have to press Enter there to confirm, but on the level itself, you just press the A button.
But I enjoyed it!
