Heya, fellow Indonesian here. I think part of the main criticism towards this game concerns about the game's length and replayability. I know the developer has said that it has more than seven levels (just how many additional levels, I wonder?), but even then it still feels all too short for many other players. I think it'd be much better to also add some custom level support. Even if it may not be the easiest thing to implement, I'd be happy to see the developer put this into consideration.
