The playability wasn't good but definately has possibilities see Map Design
It's tough to judge the balance because although you get free units...you have no possibility to upgrade them...You should get Trade posts and some indian workers to gather the tons of available resources.
The creativity is cool...and with some adjustments to other areas could be cool
Map Design: 2
The map is full of resources on your little island...which I didn't get...why resources and no way to gather them? Also a trading post or two to upgrade the units would be nice...you give resources at the beginning, but there's nothing to spend them on. Also if you take your canoe full of guys right against the edge you can drop them off on the island and walk right around the wall...
There aren't really any instuctions to speak of...and absolutely no storyline...adding some would help
The scenario has possibilities but could use some significant tweaking...
