Recently restarted my first project (after reading some tips here on the forum).
But hardly started and already got stuck at the limit of 4Mega, which forces me to restructure the methods load sprites backgrounds (on this, I'm searching right here).
Here's a screenshot of the game running in the emulator:

And also a link to download the test file:

Note: still missing post codes collision (still learning as I am doing the project) that are giving me a "beautiful" headache.
