I really enjoyed this one and I plan to dive into a few more runs later on (got the Ruby for 40 so far).
On the face of it, this looks and feels little a traditional dungeon crawler but then after figuring out what the game is asking of you it becomes more apparent that it is almost like a route planning simulator.
It's clever that the encounters are a different sort of peril from what the player would naturally be accustomed to. Fighting and defeating them is actually juxtaposed to what is beneficial to the player. It reminds me of another game called 'Hero Run'.
The game's premise and design means that the game offers far more gameplay in terms of it's replay value alone. It really hammers home how much can actually be achieved with very little.
