The early game is easier than other defense games lol

Other defense games are tough before clearing like 3-4 rounds early on. But this game gives out gacha tickets generously, so I cleared up to round 15 without dying once lol On the other hand, it seems like they're stingy with money, because I'm always short on cash for upgrades hahaha Most games lack upgrade materials, but this is the first game where I can't upgrade because I'm short on money lololol
