Nice to see a fellow 1-bit low-res entry. :)
The game mostly plays well, except that the ability to break certain blocks with pressing down does not seem to work reliably and it would be nice to have some "you are here" indicator on the map (my solution for a 1-bit low-res game was to make the current location blink in inverted pixels).
Other than that, this is a good metroidvania game, well done! :)
