[DESIGN] Single-Player Objectives, Scoring, Special Abilities

[np-eazy]

Survival design: abilities make it way easier to do certain things or remove certain problems/obstructions, but we want to tune them to just the point where the ability to cleanly/strategically stack is important.

Score design:

• Lines cleared: 100, 300, 600, 1000, 1500 based on number of lines cleared at a time
• Target blocks cleared: 100, 200, 500, 2000 based on its size. Multiply by the number of target blocks cleared in this turn
• Placement combo: each time a line or a target block was cleared,

Target block types:

• Timed Target, starts from 1x1. You have a certain number of moves to hit this target
• Fill Target: grows over time, starts from 2x2. Destroys an area twice (4x in terms of area) as large as itself when filled
• Ability Target: disappears over time, starts from 3x3

Abilities are obtained by filling ability blocks, and the user has 4 slots of abilities. To use one, press the number of the inventory slot

• Bomb: destroy cells adjacent to this piece
• Large Bomb: destroy a 5x5 area
• Ray: when the piece is dropped, it erases everything in its path
• Freeze: place the piece in mid-air when dropping
• Phase: the piece can pass through surfaces
• Lock: Don't change the piece for the next 5 moves. This allows to repeat other abilities

Game Over condition:

• a timed target cannot be reached
• a fill target grows to where hits the edge of the board
• a block is placed completely out of bounds

I've been slowly hacking away at these but it looks like everything is implemented as of #55
