Half-Heart Hardcore

mod that makes all worlds hardcore and gives the player half-a-heart max health

in 1.3-1.12.2 the mod fixes heart rendering, which is client-sided
except for that one feature, for all versions it operates on the logical server (so it works on multiplayer worlds when installed on the server and singleplayer worlds or open to lan worlds you are the host of when installed on the client)
so for 1.3-1.12 the mod uses Legacy Fabric and you should install it on both the client and server but it only needs to be the (logical) server, and for 1.13 it just needs to be on the server

for 1.0-1.2, the mod uses Ornithe to load, and is only client-sided. If used on a server, it will still limit everybody to half-a-heart but it won't be hardcore since multiplayer hardcore was added later in the infamous 12w18a snapshot.

should work with most snapshots but obviously i can't test, if one doesn't work lmk and i can fix it
it does work with the infinity snapshot (20w14infinite, the dimension one)
