I love that the title screen gives the player a chance to mess around, as well as show different pieces of information. That was very clever

My best was reaching level 3 and coming some distance from beating it. After getting used to not killing myself, strategizing against enemies, and leaping over other initial hurdles- my most common issue became the computers spawn-killing me, which is fun but seems to heavily favor them if there are 2 or more active. My best counter was to fire on the way down, but it wasn't always effective unless the computers were "cooperating" with me. I think a brief pacified invincibility window is fair, at least for the player ball in these cases, because I think moving from that spawn point to a more favorable position or attack position still is legitimate
I thought the colored 'moods' were a nice touch and could even be brighter and easier to see. This would aid players against multiple computers because of having to use peripheral vision
Sometimes the computers managed to kill themselves, but it's hard to complain about that when it's easy for the player to do the same thing
The game plays very smoothly, and the unity web player required to play the game installed quickly and easily. Looks like it was a great project to test the waters
