A nice take on pong! I like it! Even though I got verry stressed!
A tip might be to slow down the wall coming after you, it feels a bit to much with all the obstacles but I think with time I will improve my skill level as well! It would be a really fun game on mobile to just take a small break if you add more minilevels and some sort of progression curve with exponential hardness with a bit of tweeking. Also maybe adding some stars in each level to force the player to slip the focus from only going down to taking some risks!
Well done and would love to see this expand! :D Keep it up!
