Good world design, good use of levels to guide the player. Camera movement needs to be adjusted, currently it is using some offset so it can be fixed to normal. Enemy on the 2nd level had been ended so your astronaut can go home safely. Wink!!

Omg love the environment art! I also felt really good after getting the powerups and the shooting felt quite good.  The music fits it quite well too. Our team of 4 tried to make a "game" too. We added a neat snowball mechanic and gravity effect like you guys. Check it out!
