Man, addicting game. It's not super hard or super cheap, good difficulty and learning curve. Nice work
For anyone wondering, Return Portal does not help get a Brilliant rating.
Also, to deal with ninjas, either spread out your towers or invest in Burning Towers or Meteor.
Other than that it was a perfect game.
It's Addictive its Fun It's Challenging has it all i already played the Level Pack Im hoping for a franchise in here the many posibilities and evolution of enemies and tower types are huge please keep it up.
best tower defense game ive played on the web
