As a gamefeel gourmet I can tell you it's a real joy to play. With a legit upgrade tree that could be made into a genuine browser game, maybe not a Steam-level product scope but a really nice small time killer. Tell me if you want to continue this one because if you don't I might steal the idea (and if you do I pinky-promise I won't). I also like the music and presentation, good job to the artists and musicians!
