Loved it! Completely forgot how time passed, addicting gameplay loop and a wide array of different turrets + powerups. The mortar ended up being my favourite because of how reliable it was.
If I had to give some feedback it would be throwing VFX & SFX in to really give the game that extra bit of juice.
Also unsure if this is a bug, but I could only see the radius of the turrets on the outer ring, ideally I would want to see the radius when I click on a turret.
Cheers!
