The reason you may have encountered problems with jumping is because you cant jump when the stamina bar is empty and i forgot to mention that in the tutorial, sorry for not making it clearer 

I didn't really understand the concept and for some reason couldn't jump anymore at one point, but it seemed cool

It's a cool game. The music fits nice to the action. It's nice to see a tutorial :)

This game looks amazing and the gameplay is really balanced overall
Nothing much to say except good job

Pretty cool aesthetic you're using here, though if you stare at it too long it goes get a bit bright haha still good! There are some bugs here and there but still enjoyable overall. Well done! 

The game has a nice aesthetic, but it's a little buggy.

Very cool production value !

Cool dynamic fps, but sometimes the jump ability does not work. Great job anyway!

Fun game but controls can be a bit finicky

Looks really good! But I also had the same issue with the jump stopping working.
