It's like some kind of... cool math games... dot com...
The vfx are really nice, with some cool sfx to match with it too. My favorite level was probably the one with a buncha zeroes in it, I like it when games have a level to troll the players, it helps the player rests their mind a little bit too when it comes to a puzzle game such as this. I was expecting a new triangle that adds instead of subtracts, and it did appear however I think I would've liked it to happen a bit sooner, just for that feel of increasing difficulty. I also wished that there were more math operations like multiplication and division. But aside from that, I think this is a really cool concept for a puzzle game, and I can totally see something like this becoming a mini game in a much bigger game.
