Example showcases:

• Use of 1D array for a tilemap and using it for collision;
• Simple movement for a platformer (WASD + space) and top-down (TAB to switch between)
• Rectangle based collision for movement and collectibles
• Integer scaling with resizable window
• Programmer/ procedural art using only built-in shape drawing
