>the game is slow
Yes, indeed. It's slow because enemies hurt a lot, you have to manage items etc. this need to be slow to incentive the player to think before move, it's not a hack n slash game.
In fact, you are making progress. If you explore you'll find upgrades, money, secrets, lore, npcs etc. I want the player to feel lost and desolated, but I know that the player can overcome the odds if he really tries his best! The looping nature of the level design is something that helps to create a better sense of space, at least is what I think. Metroidvanias do this a lot.
Again, thank you for your feedback!
