Hi Irene!
Nah, I was doing this project with 7 of us on this game. 3 artists, including me. 3 programmers (that handles unity) and one level designer. Anyways, we ARE sooo glad that you are 'having fun' with the game. We tried making a top-down game that isn't pixel and it was SO hard lol.
There are lots of methods to clear the slime stage. You can 'kite' them using broadsword and venture the whole area as you kill the slimes. If you have the time playing this game again, good luck on that try!
Hope to see you again on the next jams here!
