Don't seem to be too many deals on this atm, this is the best price I could find.

I've been playing this for weeks. It's pretty fun, especially if you liked the old games. The sets and levels look great and it's nice to be able to explore around. Would recommend.
Have they implemented any online co-op yet?
No, there's been zero mention of it as far as I know. Bit odd they wouldn't implement it though. Most modern games offer it.
