Good game concept
I love the concept, the controls are fairly clean, but the game fails at a couple points. You can't reset your upgrades or upgrade your worm by replaying levels. This means if you made bade choices on what to upgrade early on you're screwed. Additionally most games like this allow you to gain XP of some kind by replaying levels. There is no real reason to replay a level in this. As I said the concept is great. Controls good. Graphics and music are all good. The upgrade system makes the game unplayable.
