Thanks for playing! Technically you can jump off of a falling block, but it is very difficult because the blocks teleport down the grid so the amount of time the rigid body is marked as grounded is very short. I did want to fix this, but ran short of time >.< 

I used stable diffusion for the menu screen and the background screen in game (not the volcano part). I also used it to generate the rock textures of the cliff wall.  For the menu screen I had it generate the dinosaur, the meteor, and the background landscape. Then I modeled the 3D tetris piece in blender and rendered it at the angle I wanted, slapped it over the meteor with an overlay filter, then I passed the whole composited image back through stable diffusion to help improve some of my sloppy gimp work. Stable Diffusion is great for getting little pieces together and I have used it a lot for my recent game jam game (making screens, background, textures, ect.). I would highly recommend it as just a general art tool and I have seen some artists do some crazy things with it. 

Thanks for playing and the feedback! The blocks do speed up as your score increases,  and you can press the down key to force them to fall quicker in the early game, but I can see why the slow fall may be frustrating when starting the game. 

Thanks for playing and your kind words! A little practice goes a long way, my roommate seemed to get a kick out of the game after I forced them to playtest it for me and now they crushed my high score even with all of my practice from testing changes lol  

Thanks for playing and for the feedback! As far as controlling where the block goes I tried to provide an indicator with the next block to show where it would fall relative to your dinosaur, but I guess that was not very clear.

The speed does increase along with your score and maxes out when you get to 4000 points at which point the speed is so fast it gets really hard to platform around successfully. 

Working around not being able to turn the blocks made it interesting because that was such a crucial control component in original tetris. The sand blocks were introduced to help solve that, but I feel like the solution was only a partial solution. Through a bunch of playtesting I found that Easy mode (which only had 1x1, 1x2, 1x3, 1x4 and 2x2 blocks) it was very achievable to get to the max speed and survive at that speed for a time, but it required playing a little bit differently than you would in straight up tetris since you are planing what your terrain would be rather than just trying to clear the rows. Hard mode which has all of the other tetris block types did prove to be very difficult due to the lack of control (hence why I broke it into a separate mode for those who wanted the challenge) 

We had plans to add bomb blocks as well as a few other types, but sadly ran into time constraints and had to scrap those ideas. 

Thanks for the feedback as it really shows that the game was not communicating some of its features very well, and there were also areas to improve upon.
