For me it gets a 9/10 rounded up to 5/5 the only thing I'd like to see is maybe a few more towers or tower options that you cold unlock for the fun section or even have them as standard.
Suggestions:
- Poisen (damage over time)
- Shock (Hits multiple tagets but each subsequent target takes less damage)
- Morph (changes the creep into a random different type creep)
Also a new creep type I would like to see - reverse - its like normal but comes in at the exit and leaves at the enterance
