Many thanks for your feedback !
Yeah I apologize for the technical issues you encountered this is frustrating and any player shouldn't go throught such problems, we are improving ourselves to fix that in the future ( a part of it is already fixed and will be implemented after the jam voting session )
But really your comment is heartwarming and encourages me even more to create metroidvania games, there is still a long path to make things better but we'll make it i'm sure, thank you so much for those kind words :D
