*Multiplayer is buggy but still working. Both of you need to restart the game each time if you want to rematch. Otherwise the game will stuck on "starting" or "loading", or you will get empty black box on opponent's space.
*You can change to windowed mode by pressing Alt+Enter.
*If you liked songs or BGMs of the game, you can find it on Data/Sound_Default foulder with "BG_~" names.
The game rule is really simple.
You can remove a block by clicking it, and you need to make a big (2x2) block in order to get points or attack to your opponent. Also, you can rotate the board to change a direction blocks move.
On earlier stages or easy difficulty you can enjoy the game at your own pace. But as you continue the game, you will be required to search for a best block to remove as fast as you can. Both of clicking speed and perfect combo.
There are 4 modes. Puzzle, Battle, Push, IQ.
Puzzle is a stage clearing mode that contains 50 stages. You need to do some certain things like "XXXX points within XX seconds" or "XX combos within XX seconds". Each stage has unique board that will give you challange and fun.
Battle and Push modes are play against AI with different way. It's better to see the trailer how those modes are different.
Above normal or hard difficulty, AIs are really tough. So I'm sure you won't be bored by easy and liner AI.
IQ mode is a classic puzzle. There are pre-made boards that need correct solution to remove all blocks.
If you are looking for a puzzle game that can be played without any hurry, probably this mode is best for you. Other modes have time limit or opponent.
At the beginning of this game, you only have Puzzle mode to select. You need to unlock other modes or skins by collecting "CUBE"s.
CUBEs are gained by beating the stage or AI, so if you want to unlock another mode or difficulty, you have to play well. I think this is nice motivation to play, at least it won't disturb or annoy you from playing the game.
Graphics&Sounds are cute, that makes you to feel relax while playing.
Since Clickr has some bug on multiplayer and difficulty is not acceptable for everyone, I think this game won't be a best choice from all of the puzzle games.
But forusing on singleplayer and bit hard difficuly, cute looking, this is a nice puzzle game that is able to spend 10+ hours.
Also, the dev decreased price to half ($5 from $10) later 2013, and included it in a indie bundle and added trading cards now, so you can expect some newcomers.
If you are looking for some puzzle game that is different from old-fashioned style and tough enough to annoy you, I think this game is worth the price.
