Superb work!
This game is a masterpiece! Original, entertaining and will hold the attention for much MUCH longer than the average game. It took a little practise to get the hang of it, but once you're keyed in all that remains is the intended challenge, just how it should be.
The best part about it though, is the fact that it really did give you the feeling of being involved with familiar characters. Games like Futurama: The Game (for example) just seemed like a lot of other things you've played before except it happened to have the likeness of Bender pasted on it. With this beauty, you feel you're actually part of Blockhead's world, and like a lot of people have said it makes you realise exactly WHY the conscience has been so pissed off all this time. It's a legitimate expansion of the series instead of a gimmick, one that actually enriches viewing the cartoons!
Blockhead himself is as adorable/infuriating as ever, and most of my failures were due to my anger bar filling up too quick just because I couldn't resist waiting to see what Blockhead was going to do with the various objects.
I suspect you spend many, many, many precious hours of you life you'll never get back creating this thing. Take comfort in the fact that they were well spent - you made a lot of people very happy!
Buy yourself a beer! :)
