Hey - thanks for playing and for the suggestions! I like the up/down arrow glyphs showing the meter changes - I will definitely look into adding those.
I also agree on the variations - I have a few more minigames just about ready to go, but I am currently trying to come up with a fun, thematically sound way to implement them (I don't want them to be just plopped on the player in the form of additional server maintenance games) - so if you have any thoughts or suggestions, for activities/events that would make sense in the game' universe, I'd love to hear them!
