Enter doesn't do anything until a couple levels later. Use the "A" and "B" buttons! They are mapped to z and x, or j and k... also ctrl and alt, I think. Then interact with the hatch on the sub!
Thanks! I played the game and enjoyed it, my only complaint is that the levels are a little generic and easy. Maybe if you make a non-jam version of this you could make it bigger and more challenging?
