CHEMISTRIS is a tetris-like game based on Chemistry equations, designed for geeks and science zealots like Sheldon Lee Cooper in all ages. CHEMISTRIS is a hardcore game, and might be the hardest tetris-like game ever. Just remember the goal is to carefully arrange reactants and reaction conditions to generate specific products. FUN BEYOND THE GREATEST COMPUTER GAME Fun of arranging and destroying tetrominoes-like molecules with: A careful consideration not only about the stack of tetromino-like molecules but also the balance of chemistry equations. Modifications on rule of level to create completely different experience with same chemistry equations. REAL-WORLD KNOWLEDGE ARCHITECTURE OF CHEMISTRYWe humbling embrace the knowledge architecture of chemistry with: Periodic-table-of-elements-like nonlinear level select system. An universal reaction algorithm equals chemistry equation itself. STYLISH PIXEL ARTS Simple, clear and elegant pixel style arts with: Brutalism pixel arts with KISS principle. Bravely new designed
