Worlds seem the same, visuals are a bit inconsistent. The game itself doesn't really have any of the plot that the page mentions. As was already mentioned, the mechanic of shooting draining your HP without any indication, and dying taking you unceremoniously back to the title screen, are very confusing until you figure out what's happening.

Good work on finishing the game though!

Pretty simple, but I guess it gets the job done.

Not really much to comment about this, other than that I wish the "worlds" were more visually distintict instead of all looking the same, and I also wish you had made some sort of indication on wheter you're actually taking damage or not since it's kinda hard to tell. That would also make it easier to realize that shooting consumed your health since you didn't mention that on the page, so I took a while to understand why I was suddenly dying

Anyway here's a gameplay vid (I died on the 4th round sadly)
