Undertale: Gerson, The Hammer of Justice (Fan-Battle) WIP

Version: 0.1.0about 1 month ago

This is a Work in Progress version of the game I had on my computer. I won't be able to continue working on it or fix any bugs because I don't have access to the project file anymore, but I just wanted to release this so you could try out what I had done.

Game Soundtrack

2 songs

(OLD) Hammer of Justice

1.(OLD) Hammer of Justice
2.(NEW) The Hammer of Justice

This fan game is based off of Undertale's Gerson who in the original game is a shop keeper. I was inspired to make this game from something he says when you talk to him which is something along the lines of being a hero at one point known as "The Hammer of Justice".

The games battle system is the same as undertale and revolves around a same sort of style as the Undyne fight in the original game. I have also added some new mechanics to the game to add a challenge.

The game is now ACTUALLY up now~ Sorry about that I haven't used GameJolt in years and forgot you needed to switch to Early Access/Complete Stable in order for releases to show! ^^

Ok everyone, I have released the WIP from 6 years ago!

Now I won't be able to continue working on this or fix any bugs but I hope you enjoy what I had done of the game.

Hi all!

It's been a while but I just wanted to say how cool it is that there is an official Gerson fight in Deltarune!

I most likely won't continue working on this fangame but check out my video for more info below! https://www.youtube.com/watch?v=Ls0zgdxPeM8

Small Update: Ran into a small problem, the size at what I did the new sprite at is either too small with 1 pixels and too big with 2 pixels so I may have to redo it or try something else.

So I redid the Gerson sprite again to make it more accurate. I hope you like it :3
