This is a beta version of my entry for Minigame Competition #45, a space shooter called Marios in Space. This particular beta has two levels, and one boss (since I was too lazy to make a unique boss for the second level, I just took the boss from the first level and made it stronger; I'll fix this, though =P).
Screenshots:

Controls:Arrow Keys - Move
Enter - Shoot
There are also color-coded powerups that sometimes appear when you destroy an enemy. There are four types: Laser (Yellow), Shield (Blue), Speed Up (Green), and Two-Way (Red). All of them are useful in their own way. (Note that powerups do not accumulate; for example, getting two shield powerups does not give you a shield that protects you from two hits.)
Link to download. Have fun! Comments and criticism are welcome.
