Space baddies are incoming and we're UNDEFENDED! Grab a tower kit and deploy a tower. Make sure your keep them fed with ammo. Disclaimer: May cause fun. Placing towers may hinder your ability to navigate the map.

If you have issues with gamepad mapping, audio or a major stutter when the game starts, please try another browser, download a native build, or build from source. The last two things could potentially be worked around, but are pretty typical for a Bevy game on the web.

This was built solo in ~7 days for Bevy Jam #3. Many exciting ideas including even attempting to shoehorn the theme in were chopped so that I could present a working and reasonably polished game.

Nice how many hours to build that ?

Had a blast!

Cool idea.

Very nice looking game, an inspiration to all creators out there. Simple and effective gameplay, the graphics doing their job. Very nice!

Had fun balancing everything while figuring out where I could/couldn't build a turret. Could have been better with a rotating camera.
