SNKRX/todo

1. Enemy spawn points should have some markers before enemy spawns, or should avoid spawning near the player at all
2. Prevent spawning of units that cost 3 on first level
3. Prevent spawning of units that don't attack on first level

4. Rework position based units so that position in the snake doesn't matter
  Chronomancer: +10%/20%/30% attack speed to all allies
  Psykeeper: stores damage taken by all allies up to 20% max HP and redistributes it as healing
  Squire: +5%/10%/15% damage and defense to all allies

5. Stat details to each unit when hovering over it in the party section

6. Mini boss every 3rd level
  This is just a special enemy with more HP and ability to buff nearby enemies with modifiers, no additional AI or attack patterns
  ... aiming for ~5 different modifier combos that the boss uses

7. Enemy modifiers
  Grant nearby enemies a speed boost on death
  Grant nearby enemies a damage boost on death
  Explode into projectiles on death
  Charge up and headbutt towards the player at increased speed and damage
  Resistance to knockback
  ... aiming for about 8-10 of these

8. Additional characters and classes

11. Steam integration: achievements, etc
12. Hovering over a party member should show which set they belong to and vice-versa
13. Show a unit DPS list like Underlord's to the right side of the screen
14. Warriors that deal AoE damage should deal extra damage based on number of enemies hit
15. GO button is grayed out and thus doesn't say it's meant to be clicked on
16. 28/20 enemies or 4/3 wave confuses players and makes them think the level goals are bugged
17. Music for first 9-15 levels should be calm rather than upbeat
18. Crash: Error: engine/game/hitfx.lua:46: attempt to index field 'parent', engine/game/hitfx.lua:46: in function 'use' love.js:9:40605, enemies.lua:56: in function 'on_collision_enter' love.js:9:40605
19. Sage's pull force doesn't increase with unit level
20. Cleric's healing amount doesn't increase with unit level
21. Squire and Chronomancer's buffs don't increase with unit level

Boss ideas
  Pretends to be dead, grants speed buffs to enemies after death, especially if the round has gone on for too long which means the player is surviving with 1 unit

Map modifiers
  Wall spikes: walls damage you when you hit it

Engine improvements for after SNKRX release
  on_hit:
    on_collision_enter/exit are automatically called and automatically call on_hit/on_leave for each object
    This enables the definition of on_hit on each object and the question of where the logic should stay is solved/dodged
    Spurred by Wall needing to have its own on_hit function to do something when the player hits it, without having to change player code for all Walls,
    Defining on_hit on the Wall creation call for that specific Wall, and thus that specific Wall will have this behavior while other walls won't
  release tool:
    Build a command line tool that creates projects and builds them up for release automatically on Windows, Web and Steam
    All the steps for this are listed on the readme and everything about it that can be automated should
    Ideally the user should run one command for creating a project and one for building it for each platform
