What purpose does this tower have in ur map? I expected that I can destroy the T4 towers after killing the T1 middle in ur base, since it s a base tower. It should give access to the T4 towers for rats imo. But make that particular T1 a little bit stronger for that purpose. Atm I dont see it s purpose other than shooting at chasing people.
Would it make more sense to make it a T3? I dont know
Else, it s a really good map
