Pixel art to do
===============

- Player KO animation. The timeline of a KO is:
  1. When the player's HP reaches 0, "KO" is played ("falling" animation)
  2. When "KO" finishes:
     (a) "IdleKO" is played in a loop once ("lying down" animation)
     (b) Simultaneously, end screen appears
  It is possible to include some idle frames in "KO" in order to delay the
  appearance of the end screen.
- More varied attacks:
  * Sharp shadow attack (see skill icon for inspiration)
  * Circular slash? (We already have shock)
  * AOE-style bomb/meteor/etc?
- Enemies:
  * A new jumping attack for slimes for variety in Wrecked Lab (Arcuz)
  * Or maybe a flying slime?
  * Skeletons
  * More tifuciles (including mamafucile)
  * Crypt boss (Dracula / Skeleton archmagus / etc)
- Better dash animation
- Environment damage
- Particles after monsters' deaths? Slime puddles, dark enemy outlines, ...

Programming to do
=================

Core mechanics:
* Have a deterministic mode for grinding
* Use for items in battle (potions mainly)
* Infinite mode for every level
* Map events, including removable tombstones in Crypt GLOOM
* Elaborate AIs that force the player to move and adapt, not just mash
* Tutorial
* Bindings for higher score:
  - Faster waves
  - No skills
  - Reduced weapon damage

Content:
* Additional skills

Infrastructure:
* Better end screen
* Save and load scores (including with bindings)

Extra details
=============

* Have camera move? (eg. in the direction of movement)
* More explosions
* Cool-looking shaders?
* Leaves particles on monsters' death
* Leaves environment damage after spells and explosions
* Bonemeal easter egg (grow plants wherever skeletons die)
* Also the other easter egg
