Thank you so much for playing and thank you so much for this detailed feedback :D
The game originally was way more punishing, but on the last day of the jam my buddies tested it and they were dying and restarting the level constantly XD So I quickly added the checkpoint system :D
One other person also had that bug. Haven't recreated it my self tho I wonder if its a browser thing.
But it makes me so happy you had fun :)
