This level is based on the final room of one of RoberTime's Qristmas levels. In the original level, it was a pretty free style room because you could afford to waste one of the boxes. In my version... not anymore. You'll need everything this time.
I really, really wanted to achieve this when playing the original level and, after tinkering around in untimed mode for a little while... success! And, in retrospect, it's not even that difficult.
I gave you a lot more time on the clock to make you comfortable, but if you know what you're doing, my level is solvable in under 30 seconds... you just have to know what you're doing.
Original room was easy -- now I think it's quite a bit harder.
