More upgrades like "faster science generation", a sandbox mode and defense systems are missing in this game, in my opinion. The game is already good enough for a 4+ rating!
I would like better sound while fight. My two handed sword sounds like a small club when hitting enemys... how about adding additional sounds for every weapon categorie? Keep the sounds for clubs and hammers, but add a slice sound for swords and axes? Some more battle music, like the boss battle music, would be great too. However, the game is already awesome!
