Thanks a lot for your feedback!
I want dialog boxes to appears like in Enter The Gungeon (hovering the actual object), but it was quite difficult to make and a static screen is easier (but not so pretty). These dialog boxes will be fixed after the jam (I hope ;)
Rooms are too large (they match width but not height due to 32 px scale), but I do not know how to do it with an other size.
Tahnks again!
