The same concept with Hexonia but unbalanced and push you into grinding or pay after a few worlds. Enemy spawns a bunch of heroes in the first few turns. Even you are lucky enough to get some new village, the enemy can get it fast and spawns heroes by building it with crazy credit under your eyes (don't know how they can make that amount). The only good thing is that naval unit has good damage to fight even if the unit is in lower level compared with the enemy, so the map can help some times.
