Space Sweeper

This is my libGDXJam entry, Space Sweeper!


Clear a path for the International Space Station with the laser turret! Collect power ups by sending out an astronaut. You only get one astronaut, be careful with him!

He can take one hit from an asteroid, after that he'll be sent hurtling into space! Heal him by recalling him to the station (click the spiral to recall).

New level every 100 points, higher levels have more asteroids, more danger!

Try to beat your high score!


  • Q - turret left
  • W - turret right
  • C - fire
  • mouse - click to send out/move astronaut
  • click the spiral on the space station to recall the astronaut (and heal him)
  • P - pause, R - resume

Written in Kotlin, utilises Ashley ECS (and libGDX)

It's a little bit rough around the edges, but I'm still a newbie with Kotlin and Ashley. Also graphics aren't exactly my strong point...

It could do with a bit more balancing, and some music but I ran out of time.

Overall though I'm pleased to have finished something playable.
