Heya, I love the concept of this game and this is a very cool grinding game. However it lacks a feel of progression because you restart every time in the same place against the same units. While getting better people to go at it again and again is fun, it's only for a short time and the game becomes an off and on sort of thing instead of a desperate to finish. So basically, clear progress related to area and more enemy units would be good. It's a good game, and fun, however it lacks gripping factor.
