Thank you very much for your kind words and feedback! Every single button will trigger every single TNT currently on screen. Sadly due to the time constraint of the GMTK GameJam 2021 we did not implement any animations or sound for the TNT. We will however add that in once the GMTK GameJam 2021 ends!
We are also currently discussing on how to best introduce the player into the game with the various material types and we will certainly improve that in the near future.
