I’m really sorry to hear that 😭
The game can be quite difficult, so I recorded a full playthrough of all the levels and posted it in the comments. Here’s the link: https://youtu.be/sSFPcE5sCIA?si=HdS6h544FgYSih0j
I hope it helps anyone who gets stuck.
Also, holding Shift allows you to move faster and makes jumping easier.
I’m really sorry for the negative experience, and thank you for still taking the time to play and give feedback.😭😭
