I think this has promise, though definitely needs more content and play testing to iron it out. 

Personally, I never liked the hunger system in rogue, so constantly having to keep on top of that is no fun for me (I fully accept that's a me thing, and others view it as an essential mechanic in these kinds of games).

I'd like an indication of where a bomb's explosion will reach - maybe it just shows on the turn that you place the bomb, but some UI to help indicate where is safe would be nice.

It was tricky to use bombs effectively, the ghouls seemed to follow my movements away from bombs as I ran to safety so they weren't too useful.

I'd say the idea underneath is pretty cool to me and the turn-like gameplay appeals to me, though I don't know how is the competition on that genre. To me it lacks polish and more variety to be able to stand on its own.

I liked the idea of advancing into days, though a bit more lore/story would be useful to know why and how the character is there. Is there an end to it? Or is it supposed to be a how long can you go kind of game?

I liked the music, sort of gave a tense feeling to it. The starting/bomb planted sound could be a tad quieter, seems too much louder than everything else. Also I felt like when the player dies there could be a more dramatic sound.

The UI seems alright for the most part, I like the white font. The title font doesn't feel like it fits to me. The color for the music/volume setting is really hard to read when you pause mid-game.

The graphics were okay to me. I wish there were more variations for the character and ghouls, as in seeing their backs when they go up. But it works as it is, plus the bomb explosion is neat.

I made it into day 5 then day 7. The same ghoul again and again feels very repetitive. It needs more variety of traps/enemies. Perhaps you could make bigger maps some days too. And some sort of compendium with items you found through the journey, so some mushrooms could be edible others could hurt you, but you'd need to experiment to know it and then the player could keep track of all elements he interacted with. 

Overall I had fun with it!

Edit: I forgot to mention this but, I thought the game could be slightly less punishing for invalid moves. When I'm facing the wall and try to move into it, it counts as a move. Then I lose oxygen and the good gauge, while ghouls walk. That seems a bit too harsh on a mistake.
