Though it’s a good idea and quite engaging, it’s actually a lot trickier to manage it in real time, not to mention it’s also very much makes it so the medium needs to be a touchscreen or a mouse-keyboard combo.
The game’s design is around being usable to controller as well, as that’s actually the medium I am more comfortable with.
I would put some time pressure, but already placing pieces without rotating in itself is actually a bad idea in a hectic situation and makes it even worse for those which Tetris is not a game they commonly get back to. Especially with how the “piece bag” in the background worked.
I wanted it to be a relaxed experience for the game jam, so I designed it around how long you would take to get 100 lines. The lower the better. Sadly, that is not conveyed in this case due to running out of time.
Thank you for your feedback! I always like to see my approach challenged in game jams and see what I can do better. :)
