Hey! Thank you for the feedback!
1) Completely agree, will be addressing this in a future update!
2) That's fair, I coded them so if you jump perfectly before you get to them you can keep the run going.
3) I agree, it was a stylistic choice as I liked how it made it look but I can fine tune it in a future update and try and make it less blurry!
Overall, thank you for your feedback, I'll definitely consider it as I work on future updates!
