Would be nice to see Tip-text about map. For example after level start.
Like "Press M to open map" (i played final version on 3 level deep - not knowing that the map exists)
Little info and not intrusive tutorials is Very important
Also small Icon button on screen for "Mouse control" will be even better
And as additional feature request: Will be awesome in future to have Mouse control for movement instead of AWSD\arrows
at least 6 icon buttons for directions and turns
But also will be nice to have alternative mouse control like
Mouse cursor on center and top of screen - move forward
Mouse at botton of screen - move backward
Mouse on top left and right corners - turns
Mouse on bottom left and right sides - move left and right without turn
