i was a fan of your previous dangerous dungeon,i even contest with my friends who get through it first.
this game is very good too,but too short. As other reviewers said,you should add save status before the room of the boss(not sure if intended though). The boss only took me 6 times to beat,with all hidden fruit found. So i assume that you want to make it harder that you didnt put a save status before the final boss. But for me its very tedious and tiresome.
this game is much more slow-paced though,so i personally still love your previous dangerous dungeon,the timer restrict really makes it exciting and challenging,while this game focus more on exploring. For me, walking way back when you get certain key/item is very tedious and repetitive.
