Hive Leader

Downloaded and played, and it seems interesting, BUT! I stumbled upon a red tent belonging to a merchant somewhere in the north, and he sells various items for 1000 coins. After 20-30 purchases, I bought some kind of evil gladiator who kills any unit with one hit. Plus, they gave me wings so my hero could fly. After that, of course, it became very easy to complete the game. You need to somehow remove this merchant from the game.
