This is kind of it's own engine in an engine, to make Undertale fights with Block Tales Physics! Press Z just before you get hit to Block, In this battle, You normally take 2 DMG per hit, but if you block you only take 1 DMG. The Blue bar above HP is the Cooldown for blocking. SP is self Explanitory, special Skills in the Act menu cost SP. The Right Box is your effect, so far there's only Poison, which deals 1 Hp to you every turn. And Freeze, Making you slower and take 1 DMG at the end of the effect. Version additions: Act menu rework with 4 options Act, Doesn't work in this fight, only add if you want to add an pacifist route to your fight Power Stab does 3 SP for 4 dmg Dynamite uses 5 SP for 5 dmg, useless basically, it's only there because yes. Rocket Boots aren't here because they would be hard to code in (And probably OP) :/ Ghost Potion makes you immune to all damage for 1 turn, but it skips next turn, where you are vulnerable.
