Yep, I heard about the grid and makes so much sense. If it helps, the area shown is 7x7 from corner to corner of the screen. Also a case for color blindness since the circles all look the same.
The original concept was that you need to pause at the last tile to complete the level, but any extra action will result in the correct spot landing, and once you win it doesn't continue executing. I also would've added some timed challenges into the levels where you would've had to stop for a few turns before continuing, but the jam deadline is boss.
