COMMENT CONTAIN LITTLE SPOILERS

I finished the game and got ending A, apparently the best one. It left mixed but positive emotions — not all is lost, a new life is beginning. When I have free time, I’ll try to get the other endings, but I suspect that if I choose another route in A line, that will be the worst outcome. Overall, the game is not bad, especially the "boss fight" near the end, which reminded me a bit of FNAF. The main problem is the "unnatural" extension of the gameplay. The doors open too slowly, and the same goes for the movement of some platforms. Also, the collisions aren't work well, but I know it’s quite difficult to make.
BTW, 5/5
