MineStrike.fun
MineStrike.fun is Minecraft-styled io eating and fighting: start as Steve with a wooden sword, eat cakes and cooked fish to grow, dodge the poisonous potatoes, and climb fifteen forms — bee, creeper, Enderman, all the way to Herobrine — by cutting down smaller players.
The level ladder gives the arena rare structure: every fight either feeds your evolution or funds someone else's.
Tip: attack from the left so enemies sit on your sword side, and swing first — the game rewards the aggressor in equal-level trades. More block battles at battle games.
