This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

It's not just the pixel art but the rest of the game as well.
Maybe because it's not limited. If your comfort games were in RPG Maker, then 24-bit pixels are right, but good art is wrong. If they were on consoles, they should be aggressively paletted and tiled.
Try homebrew. An NES or SNES game will always look about right, because breaking those limits is a thousand times harder than embracing them.
