How does it indicate that? I just got a number '104'. I checked H as you asked and it says it's a 'sum of levels of all nearby monsters' - how can I possibly use this number to actually solve anything? All it does is give me a very vague idea of a danger level.
Like a 'level 80' can mean there's one level 80 monster that will kill me instantly, or that every field around it is surrounded by a level 10 monster. There's no correlation between monster placement and the number.
There is option to flag mines, but like I said, it is impossible to predict where enemies are.
Not only that, but maps are so filled with stuff - sometimes completely meaningless stuff like a brick wall - that don't show the threat number. It took me a bit to realize the sword icon means combat, but I get it now.
It seems impossible to play this in any way meaningfully without dying after 2-3 moves. Worse, I do not understand how I could prevent dying if the only thing I can do is click tiles. Clicking tiles will almost always result in me losing health , and I cannot actually do anything to recover health if I don't get lucky and find a potion.
Currently, you're completely at mercy of RNG that you won't accidentally click a level 100 monster and die instantly.
In fact: can I even level up? I played this game 20 times and haven't managed to level up *once*.
My recommendation would be to: make monster level distribution uneven, making it so low level monsters are MUCH more likely to appear and high level monsters are much more rare; and heal player for 10-20% of health every time they click a tile that does not have a monster in it.
