Obviously a fix for the frame rate is to play it on the desktop of course. It really doesn't take away from it being a puzzle game. The keyboard input remains consistent, so the frame rate drop doesn't make it unplayable. I do find it a bit tedious that I can still walk into the spikes while they are up and get myself killed on accident, but my poor timing is what's at fault if I fail to get past them. I had to think about who I rescued first, and in what order they should be rescued, so I don't indirectly mess it up for myself. Also which tiles I walk on, because at some point I didn't know how to retry the level if I got myself trapped in a corner with the villagers. I learned though when I pressed escape. The art direction was managed well for model and level design. I also like that the main character was chosen to be a plague doctor.
The game mechanics are built as is, and done right. Being "Snake" was what inspired it. It has its own twist with rescue order as to make you think about more than going straight for the finish. Some puzzle games are infuriatingly difficult, and some are still challenging but feel satisfying to learn and complete. Thank you for this experience.
