A downloadable game for Windows

Blow up wave after wave of asteroids to progress in this arcade survival game. Pick a ship and purchase powers to fit your play style. Improve your ship to gain an edge over the various space hazards you will encounter.


  • Mouse: Aim
  • Left click: Shoot towards cursor, buy item, pick menu option
  • Right click: Move towards cursor
  • W, X, C: Use bought abilities (can be changed in Settings)
  • Space: Finish upgrading
  • Escape, Enter: Pause

This demo contains 3 ships to choose from and 8 waves to survive through. Please note: various features are unimplemented, among which saving, unlockables and a few powers.

Known bugs: Buying something sometimes causes background stars to glitch out. Background stars carry over from the game to the menu. Game experiences slowdown when reloading.

@steroidal began as an entry to the June 2014 AGDG Microgame Jam. I worked on it on and off for about a year before putting it on hold. This was mainly due to dissatisfaction with my own design decisions. I do have plans to revive the game eventually, but it'll likely involve starting from scratch.

Install instructions

Download and run the .exe. The game does not use extra files.

Note: the game will launch at full screen. You can change this in the settings.

Hello! I really enjoyed your game, it was fun to play, looked great and had a nice difficulty incline! I made a let's play of your game here~

Oh wow, this made my day, you have no idea!

I'm glad you liked the game. I'll be remaking it at some point in the future, so your playthrough is going to be super helpful for determining what worked and what didn't.  The new version will be much faster paced, among other things.

Asteroidal is the "official" name but I've 100% considered going with Steroidal... I think that's what the hardest difficulty setting will be called.

Anyway, I'm digging your channel. Good luck with your future Let's Plays!

Huzzah! I'm super happy you liked my let's play and it meant that much to you! :D

Glad to hear you'll be making more in the future, so good luck to you in your future endeavours and thanks for the complements!
