Thank you for your feedback !
Firstly I really dunno why the mouse cursor didn't show up , maybe if you closed and reopened the game would fix this problem idk.
For the parkour section , I agree with ya maybe I didn't make the best platformer movement but i'll try to improve it next time . Thank you for telling me all the issues tho .
For the undertale section i've made the soul hitbox smaller than the heart and the attacks hurtbox too. But idk maybe i didn't make it small enough?
Anyways I really appreciate that feedback and you helped me a lot so thank you very much :D
