Unnamed first person puzzle game

Disclaimer: Lot's of updates have been made. But I was too lazy to get new screenshots. While the screenshots will give you an idea of what to expect. There are noticeable differences in the graphics and stuff.

This is a 3D First Person Game. The goal is to get to the end. You can pick up and move around blocks to solve puzzles. You have a gun to shoot at the blocks to make the hit detectors that are out of reach of the player to open doors. There are missile launchers that get triggered when you enter an area. You can place platforms to build paths and solve levels. There are no AI enemies in the game. Name still not decided. Sound design not great. Made by a 13.5 year old. You can suggest some names or ideas for new features.
