Splatsplasm

Playing as an astronaut, and starting in your own ship's control room, you then board a creaky, abandoned spaceship where you'll fend off relentless waves of weird alien creatures in various arenas.
Start off in campaign mode, where you’ll unlock a fancy new bat for each level cleared—because apparently, you need a collection of bats to master this alien-splattering art form. Each bat changes your gameplay and somehow makes you feel like a ninja and a DJ. The beats are infectious, the timing is crucial, and the splatting? Well, that’s your new life now. Splat the aliens against the walls until there is enough alien goop on the wall to dissolve it, and reveal the next room...
Oh, and the final level? Let's just say the "bat" is so bizarre you'll wonder if the developers were sleep-deprived or just trolling you.
A couple of words of warning ....Watch out... you really don’t want to hit the sponges. These little traitors will clean the goop off the walls and you can watch your progress go sliding backwards.
And the alien waste disposal system? Yeah, that’s running too. Miss a beat, and if your head ends up in one of those purple waste streams, well... let’s just say you’ll find out what real garbage day feels like. We warned you, but hey, you do you!
Once you have mastered Campaign mode, all the bats and levels you unlock are now available to you in Fun mode!
In Fun Mode, the task is simple: Smack as many aliens as you can into the walls, because why not? You can groove to the in-built beats or go wild with public domain jams you find on the URL browser. Thousands of songs for hours of alien splatting... just what the doctor didn’t order.
Splatsplasm is pure stress-ball energy. Splat your way to inner peace or at least work out some road rage after that person cut you off in traffic today.

Get splatting, and may your walls be covered in alien goo!
