nice game the u + p thing took some time to get used to not used to having my hands on that side of the keyboard well not my right hand anyways. I like how the jam page version lets you go to the next level even if you run out of health lol. Played the version you linked to some one else.
I had a issue with this area.
I went to far to the right and fell off the level and the game got stuck there and had to restart. That was on the not working so well version since it let you go past levels if you ran out of health
The one where you can die I jumped into the 4th platforms in this area and got stuck in it
and the game locked up sadly.
