got into an argument and then made this game

the Mac and PC versions are pretty different

My first submission for the 'Build me a performance space' event. I wanted to make something more dangerous than the other spaces I've experimented with. At the bottom of the (bottomless) world there are another two performance spaces in the same style as the other ones I've made, though here you are deciding what objects are there to play with by you interaction with the larger space.

This game is inspired primarily by ZiGGURAT, Outpost Nexus and SpaceInvader! The news ticker is inspired by Super Mario Sunshine. The tractors are inspired by Team Fortress 2. The environment is loosely inspired by Return of the Invaders.

Defend the lone frontier town, Crater Bulb, from these brightly coloured invading ships! Bounce shots off the floor of the crater to attack airborne and ground foes alike. Charge up to fire one of three different shots, each with unique abilities and purposes. Beware: if even one enemy trooper reaches the city, they will immediately surrender! Undoubtedly, heroic sacrifice isn't the Crater Bulb citizen's top priority.

Guide Shellmar the blue turtle through the perilous blue caves in search of treasure!

Shellmar has the special ability to repel bullets by holding his shell over his head. Shellmar is not very strong, though, and this soon wears him out, so he can only hold his shell over his head while standing on the ground and for only one second at a time.

CONTROLS:

Left/right: Move
Down: Cover Shellmar with shell
X: Jump

F4: Toggle fullscreen
Esc: Quit
F9: Take screenshot

I was in a river in Zion Canyon most of Saturday, so I missed this KotM, but I've been itching to participate in another one for a while now and figured I'd rather be late now than wait for next month.

I've been wanting to make this game's basic idea for a while. It became a somewhat different thing.

You must defend cyber node Proxis from the shapes.
Squares must be shot with the same color.
Triangles must be shot with the different color.

And a third one. This is the last, I swear.

Yeah I made another one.
