• I like the concept of collecting resources through rewards by fighting enemies. 
• Choosing between 3 locations is nice to let players strategize.
• The icon of the crafted item is/seemed the same as the resources used for it. That made it appear that nothing actually happened. Perhaps a simple colour change of the crafted item is enough to indicate a positive result.
• The difficulty jump from the 4 crows to 30 octopuses was a bit too much :) The game did not give me enough feedback to how much I needed to improve to continue. So that is where I quit. Perhaps damage/health numbers could help here.

Cheers,

Rob
