I made this heavily Cave Story-inspired metroidvania game when I was a kid. Scratch was not the best engine for this (hence the lack of enemies). The game is now defunct and buggy on modern web players, and bugs make it impossible to proceed at a certain point. But it works somewhat well in the Scratch 2 offline editor (it was originally made in Scratch 1.4). So I made a demo video showing all of its features, viewable below. The game unfortunately is unfinished, and there are only three power globs to collect, but collecting all of them is shown here!
