Tactical Tetrominoes

(Made in 7 days for 7DRL Challenge 2022, original jam version's a Windows executable labelled "(Original 7drl Submission)", browser and other downloadable version's updated with some QOL tweaks but gameplay is ultimately the same between both versions, see development logs for changes)

Rules

General Stuff:

• HP is indicated by the amount of sides remaining on a shape

Player Actions:

WASD/Arrow Keys to do one of three actions: Move, attack, or hit a breakable wall. You can also use the mouse to click and drag tetrominoes from the top-right onto the grid. Press spacebar to rotate tetrominoes while they're held. Press enter/shift to confirm your piece placement. Tetrominoes cannot be confirmed over walls, the exit, or existing tetrominoes on the grid.

You have 2 actions per turn (shown by the 2 dots under the player). Using a tetromino will end your turn.

Tetromino Effects:

L - Life: If player is inside tetromino area, heal to 4 HP; If enemy/coin is inside tetromino area, give them an "hp aura" which overheals the player by 1 HP (max HP via overheal is 8) when they're killed/collected.

J - Jinx: For every enemy type and coin pile inside tetromino area, remove all alike enemies and coin piles except the ones inside the tetromino.

O - Obstruct: Spawn breakable walls (only breakable by player) in tetromino area; Can be placed atop enemies and coins but doing so will remove them and placing it over yourself kills you.

T - Transform: Turn anything (besides yourself) inside tetromino area into something else (either an enemy, coin pile, or breakable wall); Does not work on tiles occupied by an enemy and a coin pile simultaneously.

S - Score: Any coins inside area get their value increased by 1, any enemies inside area get "coin aura", which makes them drop a coin on the space they occupy when killed.

Z - Zap: Deal 1 damage player and/or enemies inside this area or any other tetromino areas adjacent to it.

I - Idle: Any entities inside tetromino area will remain idle for 4 turns. For enemies and the player, they can't move and their turn's skipped; For coins, they won't disappear for that turn if the player collects them.

Scoring:

When you reach the exit, the amount of points you score is (coins collected multiplied by lines made), where "lines" are full columns/rows containing a mixture of singular squares of tetrominoes, walls, or the exit, without any gaps.

Other Tidbits:

• The maximum amount of coins that can be on a space is 4.
• Enemies that don't have a path to the player won't move.
• Swirls appear every so often to spawn enemies after your turn's over, they can be attacked to disappear and cancel their enemy spawn, and they're also affected by tetrominoes too.
• Tetrominoes are generated via the 7-bag system, like in modern Tetris games.
