Once I got to the point I unlocked the extra robots I had lots of fun, it's a great concept that has lots of potential. My favourite part of the game was when I realised I could leave a trail of oil around the level and drive into the fire which would light up my big trail of oil that was very cool. This is a very good game and I really enjoyed it. Only change I would say is to only have the UI elements related to robot changing visible when you have multiple robots.
