Thank you! :D It would be really cool and we did try to aim for it but time limit is hard :P
I am not really sure what libresprite contains exactly and what is the difference as I am mostly only using Aseprite but I can guarantee if you plan to spend hundreds of hours in it anyway it's totally worth getting. I create ton of plugins for aseprite for myself and they help a ton in speeding things up, so from my perspective it's worth it for this reason alone :D
