Man can not to talk about Chime and not mention Lumines or Tetris. Chime lends the blocks from Tetris, the grid and the general feel taken from Lumines. Chime has also more similarities to Lumines. Both are music themed puzzle games.
The music consist of five different electro tracks. The Steam version coming with a extra song in form of the Portal song "Still Alive". Each song having a three, six and nine minute version. The songs also use effects from building the quads with each sequencer sweep. Songs are relatively pleasant even for a non fan of this particular genre. Except for the Moby song which just repeats the same phrase over and over.
Visually the game is very simple with it's stylish colours theme. Each song has their own colour and unique set of blocks. From a quick a clance once might confuse this with Lumines even which is a compliment.
Chime has two modes for each of six songs. Besides the normal time mode there is also a free mode. Which as the name implies has no time limit. These levels end when the grid is 100% covered, strangely without the multiplier aspect. Other reasons to keep on playing this is the Leaderboards that track players score from the main mode as well the achievements.
Six lukewarm electro tracks and lack of challenge won't really last too long. At least you are giving money to charity when buying this.
