What you’re asking is theoretically already possible using SIMPL’s Canvas feature. I was putting together an example to post, but while doing so I discovered a hidden bug in the DrawText instruction that affects the final result. I’ll be fixing it in the next release and will share the example I mentioned for creating color ASCII games with the Canvas at the same time.
As a side note, since I see you appreciate SIMPL, could I kindly ask you to rate it 5 stars here on Itch and maybe give it a like on AlternativeTo.net? This would help give the project some visibility and help other people discover it. I’d really appreciate it.
