I made this cuz I wanted to try to make all 7 souls, and I think I did a decent job. You fight Matt, and I nailed the animation. This game is customizable! Change the settings to your liking by hovering over the "Customize" tab. Buttons: Buttons are boxes with an orange outline that you can interact with [Z]. SWORD ICON - Attack Matt BAG ICON - Heal yourself Soul Colors: RED SOUL - You can move around. ORANGE SOUL - You move indefinitely, with the direction within your control.

Toby Fox for Undertale Underswap for the orange soul mechanic Some guy for the cyan soul mechanic If you want to use these, then at least credit me. UPDATE LOG: V2.3 - (Nov 2) Recoded a few things V2.2 - (Sep 29) Changed the blue soul attacks cuz the previous one was impossible to dodge and changed how damaging works V2.1 - Modified shield sizing and fixed the red soul movement. V2.0 - (Aug 18) Major update! Changed many assets to be pixelated, added mobile mode, added functionality to the customize options that didn't have any, changed the bullets for the cyan soul, made the default soul size smaller, and several bug fixes! What a great update! V1.9 - (Aug 12) Changed Matt's pose a bit, added green soul-related sound effects, tweaked purple soul bullet spawning, and added more options to the customize tab! V1.8 - (Aug 11) Added more bullets to the green soul; yellow arrow and the turtle shell thingy from deltarune chapter 4 secret boss fight turned into a white oval. Also fixed some bugs. V1.7 - (Aug 10) Changed the music (the old one is still available within the files), changed the damage sound, and tweaked the cyan soul a bit (added an outline that'll appear when a bullet is near the soul, accompanied with a sound.) V1.6 - (Aug 8) Added smooth animations to the green and purple souls and added Karma compatibility with the green soul attacks. V1.5 - (Jan 21) Made the green soul stay in the center, added function to the "Change Soul Manually" in the customize menu, changed thumbnail, and tweaked the yellow soul a bit: Added 2 types of boxes; Indestructible (The one with the X), Destructible (The one with the O). The indestructible one is self explanatory, your bullets can't affect it. The destructible box can be affected by the bullets, and if you fail to shoot it in time, it creates a dust cloud that damages you. --2025-- V1.4 - (Nov 23) Added Music, made the game customizable (There's still some options that don't work yet) and made it so that the buttons will fade away if you don't interact with them fast enough. V1.3 - (Nov 20) Added sounds V1.2 - (Nov 13) Fixed the fight button for the purple soul so it makes a little more sense. V1.1 - (Nov 7) Fixed the fight buttons so you can reach them when you're green and blue, added numbers to your HP and the boss', and fixed the blue soul. (What a rough release...) V1.0 - (Nov 7) Release
