Sweetspot for buying investmenst shouldn't be hard to find, nor the hidden angel purchages, nor the anti-idling button. Please focus on gameplay next update.
I started with giving the game a 4-star rating, but after getting destroyed for 20 times on map 3 of the second world, i'm thinking about giving it two stars. The RNG keeps giving me care bears which are just 2 strikes away from a sure death. It's frustrating and upgrading the carebears doesn't seem to do anything. PM me once corrected.
