3D isometric action puzzle game with blocks. Blocks of different types fall on the moving lane and it is your job to make sure they never get to the end of the lane and do not fall. You have a "block of cannon" at your disposal. Move left or right with the arrow keys, shoot blocks with the SPACE key, try to collide blocks of the same type to eliminate them. The indicators are on the left side. The larger circle (green) indicates the block that will come out of the barrel after pressing the fire (SPACE) and the smaller circle (yellow) indicates the type of block that will be converted, which will give you time to make decisions strategic. The game is a game of intense action logic with strategic moments, thinking about the future, etc.
It will take several games to get used to the rules, however, there is also the instruction page in the main menu of the game.
