very cool game but there is a very similar game that is not 2048 and i liked in this version that there are more levels but I think that all the levels are a bit easy and i think you should do that the player will be able to freate his own levels. However this game is fantastic☺
Its calld Hivemind, here is the link: https://demberg-studios.itch.io/hivemind
They are not very same but they have the same concept. However your game is better, a lot better!
Its a great achievement that your games are similar and your one is better because Hivemind was in the top 20 games on the GMTK Game Jam!
