Who's got the first place? Why, I do!
Now- the fact that someone decides to climb to the top of leaderboard is a strong indication they liked your game. The difficulty is perfect for a game like this. I couldn't get to 100%, but seeing how I'm in the first place, I think that's not the objective :)
Graphics and music were clean and crisp. The controls- precise, and in a game like this one it's super important. I didn't love when the shapes would disappear, a the additional pentagons that could hit you didn't really affect the gameplay (there wasn't enough of them to pose a challenge).
As for the theme. This is one of the games, that focuses more on the shapes part of the theme, than limited space. I guess the space that allows you to pass becomes more and more limited. What I'm saying is there could be done more with this.
Over all- great game, that's elevated by the inclusion of online leaderboards. Keep up the good work!
