Age of Giant 4

I'm giving 4/5 because of the sweet graphics and well built main screen, with instructions, options and everything else. The overall design could be improved, the text windows could be a bit more neat.

Big suggestions: make the game a bit more difficult, cause it's way too easy and it gets boring after a while. Make more upgrades and give them some cool descriptions. Make a Bestiary with all the different enemies, some creepy descriptions for them too. Don't make them com in pairs, it's too easy to kill them, and give them special abilities, like, some birds lay eggs (mobs), some monsters can jump, others can regenerate, whatever.
Could be quite an awesome game, work on it :) :)

too easy, should consider making multiple stages with multiple waves each. Instead of adding new numbers to the title with only a slight difference with previous same game(auto1/5 for some users), make more difference, features, improved sprites and sounds, upgrade system should include passive upgrades. add stories, achievements. Please not the almost* the same* game with new titles again most Kong users hate you for these "spamming game" issues. If you ran out of ideas to make enough difference, try updating it instead of publishing as new
