Game has removed all progress , following sound update on 24 May.

The game mentions during loading, that you can improve your tower damage there. But I cant find it. Do you have to unlock it first or something?

I have opened Fire Spear and Fire Circle in the workshop but can't work out how I access the Fire Circle from Fire Spear. Am I missing something?

Literally reached the point where I couldn't spend money on anything, every square that could have a tower in it had a maxed out tower. Close to 40k in the bank that I couldn't spend! LOL.

Anyone know? I get the impression it casts a buff spell on one tower every few seconds, and it lasts for a little while? The range says 2 for regular buff, 3 for big buff. Regular buffs AOE only seems to hit adjacent towers, so I guess big buff goes a little bit further. My real question is how much of a buff is it? The towers damage display doesn't seem to reflect the buff. Regular buff shows 4.1k, bur can it really add that much to the damage of each tower? That seems like a lot. Big buff says 23k!...
