That said, i played with this a bit and found some bug with the smudge tool blending[2]. It also seems browser-related as it has different behavior in Firefox and Falkon (which uses QtWebEngine / Chromium). Also the way opacity works with the smudge tool feels weird/wrong as even at 1% it seems to affect the image a lot even though it should barely make a difference.

Also in both cases the brush area remained intact (it was just 'moving around') instead of being smudged, it is more obvious in the Firefox shot because i only did a simple circular motion but can also be seen in the Falkon shot in that there is a floating corner at the top right corner of the orange box that was 'dragged' from the left side (i was doing a horizontal motion to show that the pixels above the brush were affected even though there wasn't any vertical motion to push the orange colors up to the blue area).

EDIT: I see he posted a link at the bottom of the Readme.md I guess I should have scrolled to the bottom first.
He also made this amiga demo and wrote the music for it too. He’s multitalented! https://www.youtube.com/watch?v=cc8f7zg3-v8
wxWidgets is oldschool, QT has license issues, GTK looks so-so except on Linux, TCL/TK looks ugly everywhere.
In the modern world we need some GPU accelerated GUI library. Something like the one used in SublimeText. But with BSD or MIT license of course.
That would be much more interesting for me.
It's a bit sad that a GUI library absolutely needs to be new and shining to be even considered nowadays, it looks like the whole programming world got infected by JS ecosystem anything-that-is-more-than-3-months-old-is-obsolete mindset.
The old that is strong does not wither.
As someone who has used it and preferred WX over QT for Windows based programs, the issue is not in the look and feel of the final product itself.
It's the heavy use of C style macros instead of C++ templates, mostly.
The WX C++ code looks like Microsoft Foundation Classes. I am fine with it, but for a long term project, this could discourage new people joining the project.
I suggest Slint (https://slint.dev)
The demoscene connection makes sense. That community has always valued doing more with less.

This clone doesn't do that, therefore it's not remotely like Deluxe Paint and it's disingenously to claim it's modeled on it.
this seems to be supported
I run DPII in DoxBox on Linux like this:
dosbox DP.EXE
Something I don't see in your app is the Perspective tool.
The only thing that stops me from recommending it is non-integer zoom levels, which is especially bad for pixel art.
Moving layers around was also confusing, had to click Layer → Transform → Free Transform to be able to move things around. It would be much more obvious if there was a move icon in the tool panel that does just that.
This is surprising given it's a web application in modern age, did not expect that.
