Brilliant stuff as always Sloanysoft. I really enjoyed it. Lovely little nod to 'If I was a rich man' in the music. :-) The fact you even made the map to be a Steamboat Willie is a lovely little touch too. (Or maybe I'm just seeing things!)
Really nicely done! Always lovely to see a new version of Manic Miner. :-)
There does seem to be a missing platform on the left side of 'Abandoned Uranium Workings' though! (It's there - the collision works, you just can't see it)
