At the moment, the eraser tool is still being developed
The shortcut for erasing was meant to be holding “e” or “backspace,” then clicking the pixels, but I removed this shortcut several updates ago since it caused autosave and file code bugs
I will try to re-add this tool in the next update, I added it to my to-do list (note: I’m planning on changing the whole UI design too since I’m running outta room for new features…).
In the meantime, you can use “ctrl” + “z” to erase pixels, or draw new pixels on top to hide them
(there’s also an undo button - - but no redo button)
