Nice game, but a few complaints: 1) once you complete a mission, which can happen in seconds, theres no option to repeating it, even if you still have remaining "health"; 2) each mission consumes a limited supply of health, and the only way to continue when health has expired is to make a purchase (or wait); 3) in-app purchases are very, very expensive - were not talking a buck or two, were talking $5 to $15 and up; 4) to access certain portions of the game (to buy a bow, for example) you MUST make a purchase; 5) once the main levels are completed, the "bonus" levels are set up such that you can only play one mission every hour....unless you pay. Im all for supporting the work that goes into a good game, but this strikes me as a greedy cash grab. If you lowered your prices people would be happier to pay, and would do so more frequently.
