I enjoyed this game it was quite fun, I did find it getting a bit hard and found my self continuing to play in order to practic and kill the boss.
I did find that spamming jump while not using a direction sometimes did a extra high jump, And the story was a bit hard to follow I think it was due to the wording used in the text. Also im an idiot so when I was in the tutorial I was trying to move the character with the keys shown and didn't realise I had to click the circle to move to the next explanation... Maybe you could make it easier for my kind lmao. I think the closing scene could of done with some nice words to close out the game too.
All in all I was pretty addicted to the game, really good work.
