This game... this game is just boring. I mean, it takes no skill at all. All you have to do is spam clicking, and spam upgrading your strength.
This game could have potential. I mean the concept of it is brilliant, but the game itself is not. Some advice from me would be:
Have worlds with different backgrounds and music to match the enemies you're fighting.
Make it more of an RPG style, where you can take damage, etc.
Add a maximum of people you can have with you at a time if you do the RPG thing, and if they die, replace them.
Upgrade the art designs. They're just... not good.
The only reason I played this game till the end were for the bragging rights of all the medals. Besides that, this game is alright
Oh, also, add a hub area where you can upgrade after every number of fights.
Sorry, but this game only gets 2 stars from me.
