LinuxPhotoshop alternative for pixel graphics

Hello everyone!

I switched to 100% Linux not long time ago (Serenity + 5) but I'm struggling with the replacement of the last but seemingly simple workflow, that I have used an overpowered photoshop for when on windows.

I'm an 'ol game dev and I love firing up some compiler or IDE or game engine and have fun, today its Godot 😊😅. Long live FOSS!

I'm doing about everything in 2D pixel graphics, mostly because I have a stock of unused and also because I like it the most I guess.

So to the workflow!

Modifying pixel graphics:

The pipette must take only one value, not some mix of say 2x2 pixels

The pen writes 100 percent to pixels, or zero (so no smoothing stuff).

Possibility so make selections with 100% hard edges, and the possibility to erase (so creating transparency).

Saves with transparency to .png.

Bonus:

Resize without smoothing

Changing the hue in a selection

Aand that's it!

Is there a such simple soft out there?

BRW. Tried Gimp, it's just not working out for me.

Thank you so much 💖
