Got the two stars. Fun short little game, certainly worth the time I put in. Hope you don't mind a few constructive criticisms:
-The controls listed don't mention jumping, which is space. You can also move with the arrow keys and not just WASD (up arrow fires a bullet as well). Oddly enough, the in-game controls mention the arrows, but not WASD.
-Space can start dialogue, but not continue it. Had to either click or use enter
-Had to menu with the mouse, no option for doing this with keys.
-The pause menu allows you to go back to the title screen, but not back to level select, which is what I really wanted to do most of the time.
-There are MANY invisible walls, which causes problems when escaping a shark or while fighting the robot boss.
There's also a few moments of jank that come with this being a small two person project, but nothing really that stops the game from being beaten or enjoyed for what it is. I'd focus on what was mentioned here, and then maybe on cleaning up some rough edges in the movement after. Good work :)
