Tactical Tetrominoes - Update 1 (UX Stuff)

Hoi! I'm sorta interested in revisiting Tactical Tetrominoes and making a better post-jam version (as in not just graphical changes but balance changes, game feel stuff, etc.) in the future, but for now I made some quick changes for UX purposes.

Patch notes:

• Modified player, enemy, and coin sprites
• Made already-placed tetrominoes more opaque
• Added "actions left" sprite atop player sprite
• Added text to make end of level and scoring more clear (and the player can now press spacebar whenever they want to move to the next level)

The original version submitted before the 7drl jam deadline is still downloadable and is titled "Tactical Tetrominoes (Original 7drl Submission).exe" over in the downloads. The new updated version is now the one used in the web player and also has its own executable in the downloads too.
