This was an okay game at first, but it became super boring and tedious. The line drawing mechanic to match tiles diagonally doesn't work very well at all. Also, I don't understand why there wasn't any sort of penalty if you let the blocks go past the top of the grid. It just makes the top block disappear while a new one spawns it at the bottom. It makes it so there's absolutely no challenge to this game. There are no penalties, no lives, no timer, nothing. At least I could take a break mid-game while trying to get my score up to 3,000.
This game of yours just feels like it was put together quickly and lazily. The player can take as long as they want to get their score up to 3,000 if they want to get all of the medals. There's no challenge. Definitely wasn't a fan of this one.
