Cleanse The World

This is my entry to Go Godot Jam 4 - Cleanse The World. The player has to collect energy orbs and bring back to base. The theme is Less Is More, so the player carries less energy orbs when they carried more weapons on their back.
I'm really sorry for the "unpolishness" and "instruction-less" in the game, because I was too focused on fixing some bugs and modelling some models. But the controls and objectives instructions will be shown here.
(EDITED)
Now the game has been updated with changes including improvements and fixes.

Objectives & Instructions:

Find energy orbs around the geysers, go near them to collect them and then bring them back to the base. The guardians will be scattered around the geysers though, so be careful out there!
The base is that long white cube building, carry weapons from the green box which is near to the base by coming near to it and interact it.

Controls:

WASD - Movement
Move mouse to look around, 1,2,3 to equip the weapon(if you have carried one), LMB to shoot and RMB to switch fire mode(for the third weapon only).
Spacebar - Jump
E - Interact with things(Yellow NPC and green box)
Left/Right arrow - Select weapon(s), Enter - Carry the selected weapon (Only when you interacted with the green box)
Currently there's no pause menu, and the buttons cannot be pressed when you're game over or have completed the objective.
