Thanks for taking the time to play our game and giving feedback! Yea, the roombas were a bit of a last minute edition to add more interesting gameplay, but it might've fallen pretty flat. And yea the text were missions on a timer that you could select. The game definitely could've benefited from having an in-game tutorial or how to play button. We added it to our description, but definitely something to consider adding into the actual game for future jams.
*edit: I've changed the top image from being a banner to a background so I hopefully don't confuse others lol.
