Thanks for the feedback. I think making actually good looking visuals is my weakness with game jams because I just don't really think about it. I'll definitely make sure to spend more time on the visual side of things next jam.
Thanks for playing! Also a streak of 6 is not bad. After the jam was over I played a few rounds and worked out that the stamina disk can beat almost every other disk, coming even to its self only, which makes 6 a pretty good score considering the stamina disk should be chosen by the enemy every 4 rounds roughly (it's random)!
