Before anything.. I love the title that's a bloody good title.
Pretty fun idea, reminds me of Chibi-robo. And the game itself, for being made in 3 days, was a nice making of that concept.
The tank controls took a little getting used to, but it was fitting for and got me more into the mind set of being a Roomba.
It became a tad more interesting when I learned that the police-ETA-o-tron and battery was based off movement not time, didn't change a super lot but still, interesting.
It was harder then I thought it would be, mainly on level 4..
The fact two of the levels are just existing levels in the dark was a tad.. Underwhelming, I understand given time limits but still. Sorry to say I didn't even play level 5 because I didn't want to do 4 again.. If I missed some neat ending that's a shame.. But just.. No..
Last note, I would have killed for a mini-map to see what blood I hadn't cleaned up yet.. Not much to add just, that would be nice.
So yeah. Neat little game.
(edit, audio was a little lacking also, but I did enjoy the ding to tell you when you got something cleaned up.)
