While the random obstacles weren't really a problem for me, since they were just at the left (I don't think the randomizing works). I had a lot of fun playing the game! I think the obstacles being at the left were a good spot, as I think it'd be harder (and less fun) if they were in the middle of the map for example. It was satisfying to reach new levels, and I was thankful when the new balls being generated weren't just 2 the whole time, lol. I'd make the dash faster, make the game have more of a graphical theme (maybe a small robot in a billiards table?), and make the sound of combining less harsh (though it wasn't too bad). But besides that, great game! My 9 minutes went by fast. lol
