by mechanics i guess its the gameplay?
with colisions for example, theyre awful because haxeflixel doesnt allow custom hitboxes on tiles
there were supposed to be more mechanics in the game but they were so tied to the game being 3d that i couldnt really translate these ideas to 2d (ive switched to haxeflixel from away3d after 4 days of trying to add anything there)
though im glad you had fun playing it despite it being very basic!
and about sound, im awful at sound design
also im glad i gave you an anthophobia
