Doors, Diamonds, PowerUps,

Hello everyone, there are now doors and switches, as well as an additional task to complete a level (diamonds). Power-ups and new puzzles have also been added to help you obtain the aforementioned diamonds (here's a tip: defeat lots of enemies). Additionally, I've made it clearer when an enemy is hit, you can now move and fight in all directions, and enemies should no longer get stuck in walls.
