Such sweet game, really loved it, and the concept of loop was perfect here :D. The intensity you get from playing the game and the time pressure next to it is such a nice touch. Upgrades are the coolest parts for me the fact that some of the power-ups like speed can actually make the game harder rather than easier is interesting. Although everything is perfect, I really wanted to have more levels, But overall, in my opinion, that was a good, sweet, simple, and lovely game.
