Honestly really well done, I came from your youtube video and had to try the game, and even though it was an experiment it leads to very addicting gameplay as well as the ability to add more features should you choose. I really liked the menu and it was mostly intuitive.
Only two complaints, one the sound when you move gets annoying but I still enjoy the other sounds. And two I expected to be able to move with the arrow keys and died due to it.
Even if you never touch this again this is a good game that can stand on its own without getting frustrating and focusing well on its core premise. Props!
