More acts for Holoska are on Xbox Live Marketplace at the usual 250 points. Level packs seem to be appearing for a new continent every other Thursday -- mark your calenders!
Day Act 1 received the usual "hard mode" treatment. Act 2 does this as well, only by basing each lap on a specific idea -- the first lap requires precision homing attacks (even going so far as make you take advantage of the small time frame you get to homing attack *upwards*), the second lap has platforming while you ride the sled from Act 1, and the final lap is sort of a hodge-podge of running, quick time events, and precision stomping. Act 3 is a more complex version of the Savannah Citadel 2 Day drift time trial, and Act 4 has you speed off of ramps that don't launch you to safe ground... for the first time in Sonic history, this is not a glitch!?! You have to direct air boosts or light dashes or fly through dash rings to land on course... and when you reach the end, you repeat the course in the other direction.
Night Act 2 uses a new gimmick in which you light torches in the same way you melted ice in Act 1, and has a fair amount of platforming and balancing sections. Act 3 teases you with the goal ring in sight early on and has you navigate a long course to reach it. The requisite "hard mode" Act 1 is strangely absent, and the mission counter on the stage select is again off by one. Coincidence?
Unrelatedly, Top Tens are coming up soon. Cower in fear.
