great game, quirky idea with the upgrading, good ability to choose your own order of upgrades, game soon looses its charm once money builds, game quite easy once you get going, game ends up just being an aim for achievements rather than fun. 3.5/5
very good general idea but a more practical way of placing troops as well as a possible checkpoint system would be great, one lose and its all over but over all an exceptionally great game 4.5/5
