Thanks for the positive feedback. I wish I had gotten to the SFX because it has been a main criticism. Next jam I will try to keep more time to get that level of detail in.
The pushable blocks hitboxes was a trouble for me and I could never quite get it right. At some point I just had to say good enough. While testing the game I would always get stuck on some blocks and knew it would be annoying for players but I still haven't figured out how to fix it!
I am glad you enjoyed the numbered blocks. It was supposed to be binary and I was hoping it wouldn't come off as too difficult. The funny thing is that I expanded the game length by like 40% just in the last day by adding more rooms and puzzles. Most of my time in the jam was spent building out my objects. Now that I have them I can construct a larger world take my time with it.
