Thank you for the feedback, I am glad that you liked the direction that we went with for this game! I agree that the ground movement is a bit janky, that is a definitely a thing that I am looking to improve sometime. The issue with the first boss was also a really simple thing that I already fixed, but it was after the uploads were locked so I couldn't update the page, but that is how it is sometimes with these things haha.
Regardless, I am glad you enjoyed the game!
