wow, this is a very nicely done game!
only things that i found in the gameplay that were not done right is the traps. they all said something like "secondary text here" and the 2 buttons said the same thing on each. outside of the gameplay, before you start a new run, the main menus overlap one another. if you open a menu it should close any other one that is already open. outside of these relatively simple fixes, the game is great in my eyes. keep it up and make us some more wonderful stuff!
would like to mention that there were a few floors where a big block prevented me from getting into some rooms. not sure if that is a bug or an intentional game design.
beat it on the 1st try. (alternating between life sap and magic sap) so found a little loophole to stay full on everything without needing any potions
additional suggestion: LMB should be changed to Left Mouse Button. People that design games will know what this is but a generic player may not know it.
great work overall, you get a 93% from me!
