Update V0.0.4

This update is mostly quality of life changes and bug fixes; patch notes are as follows:

Knockback no longer teleports enemies.
Changed attack sprites.
Juniper now blinks.
Changed certain UI elements.
Spin attack now makes you invincible.
Modified certain enemy sprites.

The next update will hopefully add a new enemy type: the cherry. Cherries will appear in the spring and summer levels and will run up and explode when they get near, similar to a cherry bomb.
