Ooooh, that's so nice, thank you :)
Yeah, I like that little bean of a robot, very useful!
Have you tried the challenges? They can be quite hard, even once you've finished the main game ;)
(and if you do, know that I love screenshots and/or description of the levels made by the players)
I am definitely noting the tooltip advice, I think you are right... Time to go through the project and improve the user interface with bits and bobs!
