[v1.0] fix #3 Changelog

Changelog:

• Text boxes no longer stays showed in certain situations.
• When 2 defeated enemies are too close to each other, they will be coloured in red. This means, the player can't interact and two scenes wont be displayed at the same time. Also, their wall boxes no longer exist when they're defeated, so "active" enemies won't be blocked by them, and charmed enemies scenes will be prioritized for showing.
• Some enemies were fixed, so they won't stuck in the walls. (hopefully)
• Summoning Mirror was fixed. Player will be able to summon new enemies only after beating their stages. Only one boss will be summoned at a time, they'll disappear after touching the mirror again. But 2 normal enemies can be summoned at the same time.
• Fixed the Splash Art Gallery, there was a blinking bug before with many of the images. Not anymore!
• Pause menu should not display when the player faints while being grabbed by enemies.
• Controllers should also work better now. I usually play with the keyboard so I barely test them though...
• Added text messages to the keylocks before unlocking them.
