Hello folks, been a while I haven't come here!

I come here to get some feedback on the level as well on the characters animations.
The gameplay of this project will be a seek and find game. Which mean the main character have to find the missing part of her milking machine. These missing parts are hidden in every room.
The game will be in famicube restriction created by our fellow Arne which you can find the information here:
http://androidarts.com/palette/Famicube.htm so far, I managed to reproduce them thank to this fantastic game engine:
https://pixelvision8.itch.io/game-creator due to their limitations as it's still in alpha phase, I used the resolution of 256x144 which I think it was enough for this short game... hopefully.
If you're interested to know what is my code source, you can visit here:

The spritesheet you can see here:

Then here the 4 animations of idles for each:

The walk cycle that I still have trouble with:

Also here the speaking animation:

Now the first room level I created so far:

I'm not entirely sure for the milking machine... I will probably redo it completely depending of your critiques and feedback.
For the game result, I only achieved this so far:

I still need to figure out how to give some dynamic move like the gif files I made with aseprite since the game result is in the same constant speed frame... But that is only for the code part.
Oh and I managed to remove many pixels that are wasting the 8x8 space... But there might probably have more. Feel free to edit them or destroy them!
