Games A platformer game with no name

Hello !
Some time ago i've started to develop a platformer game with this mechanics, that you just run and invert gravity, you actually don't jump...
I've worked in this game just for 2-3 days, but i've ran out of ideas, so, any feedback and idea will be appreciated !

Tell me what you guys think about, the graphics is pretty simple because i'm not good in graphics part of game developing, and the game is pretty simple, but i've made some things that i like, like: Enemy, Coins, Checkpoints, etc...

Here is a video of the game (no musics/sounds yet, and that's not a trailer, just a simple video showing the game):

 

Is it so bad ? Sorry, i'm not good at making games

 

Well I like the art style for sure. It reminds me of older Atari games with how it plays.

 

Looking nice so far. One thing I found confusing was the yellow stars. From the video it seems you die if you touch them. To me they look like something that should be picked up/collected. So maybe make them red instead like the other spikes that kill you so the player knows they are dangerous.

 

I like the inverted gravity, that is kind of neat! However I do think that you need to evolve the overall look of the game a bit and make the main character have some more animation frames. I think if you are going for an 8 bit retro audience then maybe you don't need to do too much.

 

If you want to practice developing by re-creating existing games, that's fine (I think), but don't pretend it's your own idea.
