Ah it's cool to see a fellow Unreal developer! The character looks good and is well animated. Platforming works well. I wish I got an indication when I hit a checkpoint since it's not clear when I die where I will restart.
Thanks a lot for your feedbacks, we made this game for a school project of 4 days so it's still possible to improve it. If you have any other feedbacks or ideas to submit they are welcome.
I had editor warnings telling me lighting needs to be rebuilt. Trying going into your lighting settings, set quality to "production", rebuild and reexport.
