This was in the game for a while I just never made a steam post.

Place replacement .png images in the following folder (create new folders where needed):
[steam install]/SquishCraft_data/Mods/Sprites/

If you want to replace the player, name the image "Player.png"
"Squishy.png" for the catgirl

I used 500px by 500px images but you can use whatever.

If you want to replace other images I've attached an image with the names.






29/10/2022 UPDATE
You can now replace:

-> Title screen spinning heads "Stick.png"

-> Grid "Grid.png" (current grid is a square with sides equal to 1/64 of the image)

-> Outer Spikes "Spikes.png" (Image width to height = 5 : 1)

-> Lazer Beam COLOR "LazerBeam.png" (the game will sample the first pixel of the image)

-> Lazer Beam Outline COLOR "LazerBeamOutline.png" (the game will sample the first pixel of the image)

-> Background "Background.png" (sprite will be repeated for each tile)
