im working on a platformer game right now, with game maker. Ive been doing some work on it on and off for a few months, mostly doodling sprites, but I've only recently started to work on it seriously.
I'll dump stuff I do for it here as I do it and also screenshots or mockups. Feel free to play around with them and give me them' crits!
The basic premise of the game is that you have a bunch of aliens that are stuck in a large, sick labyrinth made by a some unseen evil genius of sorts, and one after the other, the evil genius lets them try to escape. Im designing quite a bunch of aliens, but so far I only animated and programmed the movement of that green three-eyed one, so you will likely see him a lot more in the screenshots at first.
Heres two screenshots showing the two "sceneries" that exist in the game right now. One is like, high tech facility and the other a cavern.


One thing I think I might change is the tone of the background tiles for the hi tech-ish area. Instead of darker blues and greens, I think ill give them a red hue, so they really contrast more with the foreground tiles.
Heres a few sprites of the first alien:



Heres an image showing some of his states, which is something related to how this alien is controlled (all of the aliens have weird gimmicks tied to them, this one gradually turns into an horrible monster as he is exposed to a certain radiation. As this monster he is more awkward to control, slower and easier to hit, but his attack becomes stronger)

And heres some sprites for one enemy ive started to draw. Its some sort of walking mine.



Heres the explosion for when that mine goes off. Ive juuust finished that one and im pretty proud of it!

And finally heres a few other enemies I thought about and made quick sprites of. The first row are like, of the same "species" as the mine, but like, they shoot at you instead of just blowing up. The second row will be tougher to beat but slower guys who spawn enemies from the first row. (Maybe upon death or maybe every X seconds, or both, not sure yet)

I should very soon have some sort of technical demo playable to show how it moves and give a better idea of what all of this looks together. Movement works, just got done with some room transition problems and such, and got rid of a few bugs involving the cavern area's slope surfaces.
