Sankaku

basically just QoL stuff

• added mouse tweaks
• axe no longer swings through wood (oops)
• removed stone and wood tools that had a flint counterpart
• WTHIT mob health indicator looks better (max heart display is now 20 instead of 100)
• added alternative recipe for flint axe (uses same materials)
• nerfed zombies a bit
• removed very many players (had significant impact on mob spawn rates)
• removed let me despawn for the same reason
