Hi, I think this a great concept for a full game. I enjoyed it. My main concern is that instructions were not clear. I was about to submit my rating when I read in other comments that you could **merge numbers**! So once I read this, I played again and I obviously found it much more enjoyable. You should really work on this - you don't even need to modify the game, you can just update this page (like, right now!) and it will greatly help you with ratings.
Two issues I found: 1) I somehow managed to drag a tile out of the playing area, this should not be allowed; image_2022-10-04_095629541.png
2) I managed to get a 3 on a tile somehow - this should not be allowed, right, being powers of two? Sorry I don't have a screenshot for that one!
Also, let us skip the intro/voiceover. I found it a bit annoying that you couldn't skip it, and the sound had way too much reverb effect, I couldn't understand some of the words.
Best!
