The tetris part was definitely very interesting. Judging from the other comments there was some kind of pattern or something to predict how it would change things, but I couldn't figure it out. Some extra feedback would be nice in the second part would be nice too. It was kind of hard to tell if my bullets were destroying things or making them bigger, maybe having the target cells be coloured or having some sound effect play when you hit the right things would help. Keep it up!

Thank you for your feedback. there is definitely the presentation part i should work on deeper for the next game. It always great to receive such feedbacka.
For the Tetris. Destroying lines that conyains the small black blocks will unlock the equivalent part in the top right shape. Each black block is actually placed in (non clear) 3x3 grid in the tetris block, which again fits dor the top right shape.
After collecting all the parts. You play the 2nd part with the built shape in the Conway Game of Life (simulation game) . the Player Shape is actually a (non animated) Glidder pattern. The entire grid interact in between grid content and with bullets you fire, and Changes according to Conways rules. So it is not obvious a bullet would destroy the Cell. It will however change their behaviour following the Rules.
