[DEMO v0.5.6] 3 new missions & aesthetic changes added to the demo

In this update I've worked on some of the feedback from you. As a bonus I've also added 3 new Explosives missions to the demo. Let me know what you think of these.

The Explosive Missions are very early in development, so you might encounter some issues (do let me know) and the score gained from the Missions might not be balanced at all (You can still get S rank though)

Full update log:

• Added 3 new explosives missions. Let me know what you think!

• Worked on the textures of the environment to simulate a better Virtual World (Is it better?).

• Made sure the heat-smoke of weapons emits from the hole of the suppressor, when a suppressor is attached.

• Made sure suppressors don't emit fire muzzle effect that lights everything up.

• Guards no longer puts their hands up, if you throw knives at them.

• Fixed issue with the game forgetting your rank, if you complete a previous mission.

• Grenades and flashbangs no longer makes guards disappear, but instead makes them fly a bit.

• Fixed lighting issue, when standing close to walls in night missions.
