I didn’t talk about any shooter game yet, so let’s fix this with Floati’n Assult.
“Z” to shoot, “X” to raise a shield, “C” to deploy a drone and your mouse to move : that’s all you need to know
With its dark-blue colors, nice soundtrack/sounds as well as gameplay, Floati’n Assult by Uminin can keep you entertained for a while, even though game sessions are generally short (because you can’t stay alive for long huh).
Game weighs only ~2.2MB, which is quite acceptable for the quality of the content.
I uploaded the game on the server, so you can try it here directly. I advise you to click on the “Darken Web Page” link just above the game : having the whole page in dark is much better to appreciate and play the game in good conditions.
My personal high score is 26650 points and I somehow managed to reach the 3rd level (without cheating, I precise). Can you pew pew Uncle Zana? (°w°)
