Ones 5x5: free puzzle app for iphone, ipad

Tadaki Tokairin has made another version of 2048. However, his rules are a bit different. In one version, only 1's will replace the empty squares. In another version, it's 1's & 2's that fill the empty squares.
What's different? The matching numbers will move across in 2 steps, as opposed to 1 step. This is nice to see for those people who were a little lost in 2048. However, the movements are too slow for me. I'm already making the next swipe.
I don't think I can look at another 2048 version.
