After watching this episode of Coding Train's coding challenge, I thought a square screen would be perfect for this sort of thing. It's not my cleanest code but it's pretty interesting to watch.

• ➡️ makes it go faster (increase frame skip)
• ⬅️ slows down (to a stop)

math experiment

Picked something simple for my first PICO-8 game. Also first time coding in Lua so the code is probably horrid.

It's basically this. I've only managed 1024 myself and I don't know what happens after 8192 because there's no more sprites after that.

Changes:

• Using sspr() instead of spr() to draw parts of blocks, so they appear to flow into each other when merging
• Animation cycle now skips if there's nothing to change, speeding up response time.
• Added instructions
• Added game over screen with restart button
• Added persistent high score (thanks tobiasvl)
