Hey, I really enjoyed playing your Color Filler game. It was very challenging and had a unique premise. There were so many levels that had me stuck and it was just so much fun. When I got to level 20 I thought the game was over and even then I had so much fun already, but when I realized the game was over double the size I thought, it was awesome. I would've paid money to play this on steam, or other websites, but being able to play it for free was awesome. I did play it on coolmathgames.com. I don't really think that supports you so I'm going to play it again on itch.io. They didn't really give you credit on CoolMathGames so I had to look you up. I really wanted to say how fun this game was and if you still are making games somewhere else I would love to play some more. This is probably going to be one of my top puzzle games of all time, up there with Baba is You and Return of the Obra Dinn. I hope your still making games and I hope you are doing well.
