I have been enjoying the game, but I have a few pieces of feedback. First, the timer stops being a concern once you have gotten a couple Silver Coins, as puzzles will start consistently giving more time than they take to solve. Second, the low health sound should probably be quieter, as it is much louder than all the other sounds currently. It also shouldn't be cancelled by puzzle solving sounds, as the sound cutting out is jarring. Third, there should be a way to drop items, as picking up items with downsides like the Sacrificial Dagger forces you to use them before getting a new item to hold on to. Fourth, shops should be able to do more than buy 1-2 items like maybe healing, and should have the money providing items removed from the pool in the shop. Fifth, the bosses should probably have a unique pool of puzzles to reduce the chance of having seen one of them earlier in the Floor (though this is more subjective). Finally, there should be an "end" to the game (or if there is one after floor 7 you can disregard this part). Having an endless mode after it is fun, but a You Win screen is hard to top.
