Well, on stream it is a good concept, but I kept on dying due to the ridiculous amount of enemies, and the resource spawn, which I don't mind it being random, but usually I have wasted pot after pot before breaking the first crystal, and trying to escape, where I would just immediately die to the floor zero boss due to either low health or low sanity, and on the rare tower two runs, I would die on the third floor, again do to the enemy spawns, and the low resources, like I understand why the resources are rare, and the enemies are quite everywhere, but there's a fine line of being unfair to the player, and being too fair to the player, I do think that once you find that perfect middle ground of where everything can work together, then it would be more of the player's fault for not hoarding the resources, but for not also thinking of what to do in a situation, otherwise, it's too difficult to keep trying, and it's not really fun to play in the current build, but I hope you can try to find that perfect middle ground that would be more enjoyable to play around with, also here's the stream on it, I did have to mess with my mic, cus my usb multi-port needs to be repaired for use:

It is very easy to get circeled and die fast but I asure you the game is beatable in the current form.
I havn't checked your recording yet but from what you write it sounds like you get circled by the enemies a lot.
Try to use the level to your advantage. Try to use doors and corridors for ground control and attack enemies diagonal whenever possible. The undead can attack diagonal too but they really prefere not to. Don't run into groups of enemies. Let them come and avoid battles in big, empty rooms.
