Not so small changes

Healing mechanics are simplified so new players have less to read: now you need just to kill 5 any enemies or perform 1 melee finishing to get health drops

Double jump added as full-fledged mechanics but not an option (now dashing at place doesn't work as jump). The distance between floors is reduced so you can double-jump to next floor

Movement with the machinegun in minigun mode is now slower (but not with akimbo) for better balance
