Thank you Mossieur for your kind words. I made the music and the graphics and I'm glad you noticed the "adaptiveness" of the music. There are actually 4 different tracks playing together, all muted except one. Once a card gets sufficiently close to the player, one tracks unmuted, already synchronized with the others, adding more layers and tension to the mood. Also (as you can notice, I'm proud of the sound design), the sound effects are all tuned to the tonality of the music (buttons clicks are pizzicatos F and the impact of the cubes a marimba an octave lower, using notes from the pentatonic scale in F, with an higher probability to play the tonic).
Being this our first jam, we focused on shipping a "barely working but also complete" game, without focusing too much on gameplay twiking that makes the game "feel good to play". Same for the QWERTY layout. There's a whole world of accessibility options or settings to implement (all of them requiring knowledge and time). We just hoped most of the people had a QWERTY keyboard (and Windows as OS).
Anyway, I really wanna thank you far taking the time to write your thought, we are both (well, at least me) very happy with what we were able to make (as our first jam).
Have a good day
