I couldn't really see the time indicator really well, maybe making it bigger and more distinctive would help.
The controls are a bit unprecise and it took me some time to get used to them. The graphics are a bit basic at this moment but I think that adding some variety to the background and the tile placement would do wonders and the player would appreciate the cuteness of it more :)
Very nice game in the end and I wish you luck in your future ones too :)
