This is a known bug - if I recall correctly, it's not deleted, but you have to restart the game for the menu to appear. I'm looking into fixing it now.
Oh that's a bug? I thought it was intended like in the pre-alpha where the game just stayed black after the ending. Or was that a bug as well? Anyway I was lucky enough to not start a new game because I was disappointed and that way I could redo it (later). I've already uploaded a no-hit.
Be prepared for 0.3 arms then, they are harder and less restrained (but not impossible like those 0.1 ones)! They are still quite experimental at this stage though.
Sounds great! However could you please make the bosses move to where the 0.1 bosses were staying for the first attack rather then letting the player do multitasking while figuring out the patterns and the movement behavior?
One side will probably used as a score/completion indicator, while the other side is for flair/decoration.
Maybe also put the payers name there?
