Oh this is good! Wouldn't expect any less of you!
Presentation is near perfect! The models are great and the shaders give them an extra layer of cool. The music and sfx are also on point.
What is great about this game is that there's... so much of it! You have three completely different gameplay modes and each is amazingly polished (ok, if I had to nitpick- in the tunel-flying level either the hitboxes are big, or I suck at judging distance). And it's funny! And the roomba can't fit under the furniture you'd really want it to fit (that's realism!).
As for the theme... it's not as front-and-center as in some of the other games. I mean, don't get me wrong it's there- every action you take is towards getting home.
Over all- another great submission. Man, I'd love to play some bigger game from you!
