Thank you so much! I'm glad you enjoyed it!
Awesome that you got it I was so unsure of how hard I wanted to be to get the best sword! In the end I opted for the hard coded sword upgrade in the first room as I thought that would give the most visual feedback of how the growth circles are supposed to work (even though it breaks the rules a little bit as sword upgrades are only rewarded after getting 3 or more enemies to die in a circle).
I'm super happy you got to see the ending twist I was afraid that people would just be like a cool boss I'm gonna close it now and miss it :D
I will for sure work on it at least for one major update with some tuning more rooms and at least one more enemy type along with things like more sound effects and a font(that one hurts my soul that I did not get it in time)!
