The concept is cool, I would really love to see a top-down slender-like game like this! Being able to enter buildings was a nice surprise too!
On the other hand, the map felt quite big for no reason because there was nothing to see for approximately a minute. The flashlight/batteries mechanic was nice but, as people in the comments were saying, it misses some kind of visual clues to let the player know the power state of the flashlight. For me, it suddendly went off and it was just pitch black. I had to spam the turn on button to create a rave-like lighting and continue exploring haha.
Overall, nice experience, I enjoyed it and I can see a more polished version with a good potential!
Congrats! :)
