There are several frustrating bugs and problems in the game, one of the bugs actually completely breaks the game.
1.Usually when you are underlevelled and try to visit level 2 the design differs from level 1, and enemies have 400+ hp, however when you visit level 2 while overlevelled the HP of enemies is from Level 1 (40-90) and the design of the level is closer to the first level (It's missing the glitchy textures)
2.When you are overlevelled and try to visit Level 3 (Boss) you are just stuck in an infinite loading screen, making it impossible to fight the boss and/or see the ending.
3.The default weapon (hand) is faster than ANY of the weapons I've found so far. Even if I occasiaonally find an axe that has +14 DMG, it's so slow that the DPS is actually lower than the hand.
4. It's impossible to properly farm for weapons, because the spawn rate of the files is frustratingly low. And since you can't get to the item pool of Level 2 (if it exists), because of the problem #1 I mentioned above, the game becomes a tedious grind.
I know this would take a lot of time to fix and rebalance, but PLEASE at least fix problem #1 and #2. This would at least make the game beatable.
Good luck with your next projects!
