Within a Deep Forest holds a special place in my heart, so I decided to replay it again on a dark winter night, just like I have when I first played it.

Unfortunately now it's more like "Within a Small Box", because on Windows 8.1 with a 1080p monitor the game is absolutely tiny with its 640x480 resolution. Even setting the game to fullscreen results in the game staying in the same tiny box, just with black bars filling up space on all sides. Is there any fix or workaround for this? Or perhaps a way to render the game at 2x or 3x the size?

Would hugely appreciate it if someone can help me find a solution.
