I just found your fan game and I'm a big fan of it! Super customizable yet true to the original looks and feel wise, resolution, pixelart, controls, sound. Looking forward to even more to be added, or the possibility for user customizable level packs or themes too maybe.
Currently I'm playing it with CRTemudriver on a Sega NAC, outputting the game without lag at native resolution.
One request though, to avoid people needing to force scale it to 1x 1:1 with a script like I did, it'd be nice to have a 1x scale option in game.
