Trigonarium is a top down twin stick shooter with an everchanging map. Fight your way through an arena of 12 enemy types through 4 different gamemodes while the map changes shape around you.


  • 4 unique gamemodes - Normal, Super, Chase, and Quick Attack
  • Normal - Fight through all enemy types with 3 lives
  • Super - Enemy spawnrates are drastically increased, but so is your firepower
  • Chase - Similar to Super but enemies will spawn where the player is standing, as you survive, more enemy types will spawn
  • Quick attack - Green enemies only, lots of spawns, one life!
  • Several powerups
  • Lots of enemy types


  • Kimmo Lahtinen - Original game in it's entirety, original art and original concept
  • Tommy Baynen - Original Trigonarium song
  • Noba - Demake programming, music and art


  • Up Right Down Left - Move your ship around
  • Z - Fire, aiming happens automatically. It will aim at the enemies close to you in order of creation
  • X - Ram your ship, killing everything in it's path instantly. Use left and right to aim your ram during the build up time
  • The arena will change size every 10 seconds or so, make sure not to stand on the red tiles when it changes!

I've no idea what I'm doing but it looks really polished.

Been fun watching this develop on the discord group.

Very cool. And very difficult. X-)

I definitely keep trying to use the ram ability to save myself when I'm getting trapped, and that usually doesn't work out for me. Probably need to get better at proactive use.
