I made a new multiplayer backend from the ground up and you can try it today! It uses P2P (player to player) connections instead of a dedicated server. What this means is that people playing other games on the same server can no longer crash your game or slow it down by summoning too many minions! Your server won't share any resources with any other players.
You can push the game as hard as your own PC (and your friend's PCs) allow!

The Enhanced Server still supports many players (technically an unlimited number of players, bound only by the resources of your computer).

Try it now in the multiplayer menu and let me know what you think on Discord!

Changelog
balance: Damage Limiter. For enemies with super high health, damage limiter allows for dealing up to 3% of max health at a time - whereas before it was capped at 30 damage. This has been often requested, because high health enemies in loop levels were nearly impossible to deal with if they had Damage Limiter
balance: Adjust loop difficulty to scale
balance: Ensure bosses keep spawning on loop levels after +3

fix: Exploit where investment rune gave extra SP on quickload
fix: Polymorph removing benefit of sharp teeth and hardened minions. Thanks @month for reporting!
fix: Quicksave "Last Turn" From saving at the beginning of a level before any enemies are placed
fix: Prevent unspawned players from taking damage
Thanks Piratesaur from Steam forums and others who reported this
fix: Targeting spells sometimes missing "Requires Following" Text when no non-targeting spell came after it
fix: Minion runes not working on automated summons
Also fixes quantity power scaling so that sharp teeth and harden minions applies AFTER quantity power from stacking summons.
Thanks @SquishyFishy
fix: Update player manaPerTurn when upgrading manaMax
This didn't affect players since their stat refresh logic doesn't consider manaPerTurn but it DOES affect player clones.
Thanks @Tingora!
