A fun concept, but it has some issues:
- it could use keyboard control for summoning units
- the summoning bar could show which units you have enough "Prada" for
- the skill tree could use some details about each unit / skill + highlight which ones you can afford or not
Furthermore, there is a nasty bug with Goblin skill where it leads to negative Prada (since it seems the clone "costs" you money) and game freeze. At that moment, you discover the game does not autosave and you just lost an hour of your time....pity....
