Insulation FPS Puzzle Horror v1.0.1 is a good frightening adventure game. I love it. Mazes are not much complicated. I couldn't complete the game because of I've pushed the wrong button. So couldn't use some objects and rescue myself. Pros: Smart AI and puzzle concepts are awesome. Good bg music and sound effects are awesome. Cons: No. Additions: Some weapons for survive and game saving system are expected.
Thanks to the Josthin Contreras, keep going, Good Luck!
