It is NOT a TOWER DEFENSE!!
It is BAD rogue-lite incremental game.
Bad becasue it has no balance (no anti-block and anti-evade options), it has strange decission (every run reqirement) to press hourglass (ui button)with your lmb entire run............
You have ammo to shoot, when you out of ammo the game is over. Main problem is it has strange RNG for hit chance. Even if you have Damage x1000 more than mob's HP, it doesnt mean 1 ammo = 1 kill. Monsters in this game have unimaginable high BLOCK-rate and EVASION, which makes so stupid gameplay and RPG-part of the game as much as your tatcics becomes nothing.
