Likely the restrictions can be circumvented with a tool like MTool where you can modify flags/variables that would determine the number of days or if you're playing on a trial ver.Author is still working towards releasing trial early December and hoping to release the full game within 10-14 days after.
The trial will end at either clearing the 1st dungeon or enough days passed in game.
Out of boredom:
Possible background choice on the screenshot:

It could also just be feature of that particular RPGM engine. I've seen plenty other games that seem to run on a similar version and have identical assets.Someone in F95 mentioned that Unholy Maiden's art and aesthetics are awfully familiar to that of the classic HRPG Ariadne back in 2015. One theory I've seen thrown around is that Unit03 is actually Eclipse Works under a different alias. If so, that's one hell of a return from hiatus.
