Friendlike base building Asteroid blasting game with a dash of tower defense.

Goal:

The center orbital starbase protects the earth from asteroid impacts. If it falls, earth falls. Mine asteroids by blasting them, and then using your tractor beam to collect the glowing pink minerals to your base. Collect enough minerals and you can purchase upgrades for your ship and/or base!

This version is beta.

This is a Unity3d remake of this Godot game of mine:

Hopefully this remake still counts for this Remaster Game Jam 2025:

https://itch.io/jam/remastered-game-jam-2025

(I originally made it for that jam, and now I see I am still eligible to submit this entry to other game jams, yeah!)

[UPDATE 2025-12-26] Oh my, what have I gotten myself into... Signed up for quite a number of game jams, including the Megaman Legends Jam. Found out that the deadline is this morning. Had to 3D model through the night to make turret models to qualify for this jam in time. Still hope you enjoy the result!

Megaman Legends Jam --> https://itch.io/jam/mega-man-legends-jam-2025

[UPDATE 2025-12-29] Okeydokey, for the Winter Jam, I managed to do the following to qualify:

- Hid Benaldju's models in plain sight, can you find them?

- Elephants shooting dark matter projectiles. Red cows with multiple udders blowing up asteroids. Indomitable snowmen being the artillery. Floating space piggy banks with giant magnets. Sheep decoy mine bombs. Yep, ThatsSupposedToHappen() ;-)

[UPDATE 2025-12-30] For the theme of the One Game A Month Jam "Sharing", well... two jets can be simultaneously controlled, sharing the same screen. These two jets can be controlled by either one player or two separate players. Both jets share the same resources, able to purchase upgrades and space structures.

Features to be added:

• radar arrows should display on only one starjet's screen
• base should lose HP on getting pummeled by asteroids
• few seconds invincibility time on getting hit
• better main menu screen
• lose condition
  
• win condition
• working health bar for the space jets
• different types of space jets to start with
• pausing system
  

What I made myself:

• 3d modeling of the starjets and base structures (except for the trees inside the orbital base station).
• Music composition (with post-production by DJ GeniusD for the track "Samsara Part 2").
• Some of the sound fx.
• And of course the programming I did! BUT,  with help from the videos from Brandon from Sasquatch B Studio. Thanks, Brandon! Definitely check out his devlogs and tutorials and show him a lot of love!  https://www.youtube.com/@sasquatchbgames
