The style of the game is great.
The player leaving footprints on the ground was a marvellous idea. I'm not sure if it fits retro game design, but certianly is a great quality of life feature, especially when you are looking for unexplored paths, while running out of time.
It would be great if there was any way to regenerate hp, for example for collecting 100000 points or something.
The game was pretty fun
