On that first tutorial teaching how to use "C". If you fail you respawn but your luck meter is completely empty. Backtracking to farm some luck points ends up being a hassle, specially since the drop of those lucky circles is not so common. I recommend having the player always starting with one every time you die and respawn.
Anyways, great game, very innovating and an amazing improvement over the first version. 5/5 and hope you get spotlight on every website you publish this!
