Absolutely wearing my Playdate out playing this game! Something about Playdate makes this game even more addicting.
If I could ask for any addition... HIGH SCORES!
After you lose a round, a screen appears and displays the score you just reached above a list of the top 10 (or however many) scores. Big plus if you can enter a 3 (or however many) character nickname.
In the options menu you could have an option for "Quick Restart" or something that lets you play the game as it is now where a new game starts immediately after you lose. Could also have a button on the pause menu to look at the High Scores list at any time.
Just my suggestions, I appreciate that you brought this title to the Playdate at all! Thanks, ThaCuber!
