Thanks for checking it out!
I tried to record a 100% gameplay video with the main ending, and, to my surprise, it takes ~40 minutes even if you know where to go.
Don't want to trick you into replaying, but there are more moves in the last third of the game ¦3
But yeah, having a more complex combat system from the beginning is a great idea! I think the game suffered a bit from a self-imposed restriction of having only two action buttons (yet I can experiment with adding a "run" by double-press on any direction button, and processing when punch button is being hold, which will give a bunch of different combinations).
