I feel like this game doesn't have a specific goal other than going to the next backroom level.
But what makes this game interesting to know is that this game really depicts a little impression of a real backroom. Infinite endless corridors without end✖️, There is no living entity or maybe there is❓, Search every hallway to find the exit🚪. Every time you successfully find the exit you will enter the next level➡️. I can say that this game could have many opportunities to change or add something to it so that it looks more like a real backroom🚪👍.
This is the best and most favorite game for minetest so far. Because this game dares to adopt/imitate the theme of the most popular game in the world, namely Minecraft. I hope there are more cool games like this:).
