You can now play on a standalone version of the game here: https://or321.github.io/noadev-mini-coins/

This version allows you to play the game on full screen, as the game is adjusted to the window size.

Also, there is now a new "practice mode" (inspired by NoaDev's latest game, Mini Sticky). Whenever you finish a level, the game will be paused automatically, and will show you the final time of the level. From there, you can press "r" to reset the level, or "p" to unpause the game and continue to the next level.

This behavior is disabled in full-game speedruns, obviously.
