A smaller update this time around targeting a few 'quick wins' to implement.

• Add iFrame mechanic to powerless form of player. This should fix the game crashes when colliding with enemies at that point of the game.
• The pause menu should now display over everything, inclduing the death transition effect.
• Tiny performance optimisation (only noticable on slower machines) through increased used of static typing.
• All mechanic based tutorial prompts should now be in-game at the relevent point.
• Tutorial level removed as it is now obselete.
• Main menu buttons re-organised slightly.
• Added discord presence related stuff.
• Steam should no longer be making you download both Linux and Windows versions of the game.
