Juts finished it the other day.
Final Fight with Megatron was a pushover.
Overall I found it enjoyable, would have liked a level select once I had finished it though. Then I could play the drivey bits without going through the game again.... Pretty easy though, only died when I wanted to to see what would happen, but then i guess its made for kids.
STill not bad, I would really like to see a sequel made. Then perhaps they could put in some combined skills (Bulkhead launching BB into the air for one and Ratchet would have some good possibilites for puzzle manipulation with his Magnet hands for example).
I liked the look of the levels. The training one for example had each of the Autobots rooms in it as you travel along. (check out the poster on Prowl's wall).
