@fjsaorin I just played it, the gameplay is nice : 2048 meets match-3 games. If it's an original idea,then congrats, I myself haven't seen it before.
A few improvements ideas:
1. I think you need to work on the colour scheme: while the pastels are overall nice looking, the mostly grey background plus the lack of yellows makes the game feel a bit cold/uninviting (remember how Ketchapp's 2048 had a warm palette all over?)
2. an intro screen with at least 2 visuals about how to play: show swipes and show 3-in-line disappearing
3. definitely better screenshots and splash image (once again, check out those from 2048 for a general idea of what might work)
4. the icon is also a bit generic, there are thousands of games in the store with the same icon pattern (4 coloured tiles on a white background) ; maybe try a more descriptive icon with 3 identical tiles and an arrow?)
Hope these ideas will be of help, drop me a line on Twitter if you find them useful.
Rowy!
