Thank you for playing! I really enjoyed watching the playthrough! I'm glad you found it responsive, there was a lot of testing and changing of values to make everything work together nicely. I should mention you could use the numbers on the top of the keyboard to quickly select a slot in the hotbar, if that's what you mean. I didn't put it in the tutorial cause thought it might make things too wordy, my bad. >.<
Also, not to be too... disagreeable? but I'm a little confused about what you mean with lack of theme. If you check your video at 3:21, you can see I mentioned "reborn" in the intro as well. The golden beds (one at 29:32), also mention "rejuvenation" which was one of the three words used to describe this theme (Rebirth, Rejuvenation, or Resurrection). The player is placed in a jail in hopes of being reborn to fit society's standards, and ironically rejuvenates themselves into being someone powerful enough to make society become reborn into something else? Idk, maybe I misunderstood and the theme needed to be about a character's literal revival from the dead(?), in which case apologies. :0
Regardless, thank you for your time! ❤️
