The video's preview looks bit as fast winning/looking-scenes, bit "blurry" in style when effects fading to next level/part there ...I like the added text in size/colours/etc. looks fancy, same as added audio, but maybe could include e.g. "costumizing your player" or "collectable points to trade-in for upgrades" or "if there's a highscore to list your ranks as top-week/day/year of alltime"?
I guess NPC's could join? Possible difficulties selectable? Tutorial-mode for beginners or skipable / campaign-mode available?
The title could maybe start then ending in scenes, because it could be an intro than just outro, I guess? Maybe with additional-features, bonus-stages or unlockable char's there?
