First of all, thank you for your comment on the art. Presentation isn't my strong suit.
"I wasn't able to fail the first game.": Yes, I haven't added a timer to the microgames so it impossible to fail that game. This was the lack of productivity on my part.
"I did like your choice to add a "tolerance" to the second one": I'm 99% sure this is a bug, but the fact that you liked it means the game would've been too hard if it was working as intended. When I was making the microgames for the prototype the difficulty should be the easiest(each microgames in Warioware have 3 difficulty levels iirc). I'll try rework the microgame to make it easier or just leave it as is.
