Please offer only constructive criticism. The intent of the GD Showcase is to help the developer create the best game they possibly can. Show them you support their efforts when posting.
The control would improve if the right button made the ship shot, and the left mouse button makes the ship move towards the cursor, instead of having the ship move towards the cursor all the time, because it's hard to aim continuously and avoid bullets if the ship is always moving towards your target.
Very well done. The wait time between levels is too long. Also, it would be cool if you included something along the lines of a bomb. Powerups too. But excellent job for having only two days to make this. BTW, what's the name of this competition?
