A Platformer game that I solo from A to Z includes Graphic, animation, and Code except for music, sound. I don't really have enough time to finish the whole game I've planned, even I made more enemies, higher alien tier, etc... But I'm happy with what I have done in a week, YAY to me...


A group of scientists and military personnel on a spaceship carrying an unidentified object from an undiscovered planet back to Earth for research. This is a historical discovery for mankind in their search for alien life. The unidentified artifact turns out to be a parasitic life form that can morph itself into any form that is suitable to its immediate surroundings to perform malicious actions. It can perform metamorphosis by hijacking a human host body to withdraw life force.

-Kill enemies and collect life sources to evolved your alien.

-Challenging game, when game over you will start from the beginning, so be careful. Learn enemies' position and their behavior, and using the advantage of your Alien's ability to win.

-Kill all enemies on the level to complete the game.

After this Jam is finished, I'll upload all of my assets for free. Includes all tilemap, characters, and animation and continues developing the game. Have a nice day and enjoy!!!

Music and sound I'm using"

I was trapped at the end

I liked this a whole lot. Played this as a part of a stream

Something is funky and the Itch App is having issues downloading it, double check your settings everything I am seeing online points to that being the issue

Not bad. Fun and somehow challenging. Good work

:D thank you, I'm so happy that you complete my game, awesome !!!
