Yeah this game has the design philosophy of "Lets add the most annoying mechanics we can possibly think of and then have half the items the player finds just help negate the annoyance of these mechanics instead of adding actual fun things to the game"

It is the most annoying type of design choice you can have in a game but tricks the player into wanting to play more by giving them the feeling like they are getting better at the game when in reality all the RNG ♥♥♥♥♥♥♥♥ that can kill you just gets easier to deal with because of the upgrades and new unlocks you get.

that being said the game is decent in a lot of ways. the art is nice. the bosses are fun and require actual skill instead of more RNG ♥♥♥♥♥♥♥♥, and it has a sense of charm to it. But this game could be at least twice as fun if they removed like half the annoyance mechanics or at least made them more telegraphed and avoidable.

As other comments pointed out, the Undermine seems to feature a lot of hazards for the sake of adding as many upgrades to counter them.
There's also a shop to buy permanent stats increase. This is more common in games, but adds to the weight of "upgrades to counter annoyances rather than granting new ways to play"

There's an important lack of polish in the mechanics themselves, which I don't find OK considering the studio already has a second game in early access.

- Some misleading item descriptions (at least in french)
- Rats freeze in place when you're jumping
- The game seemingly uses an actual 3d engine to manage height, so you can jump on top of various objects like crates, or even monsters like big rats. When standing on some of these, you will awkwardly slide off, as if they had a hidden inclined hitbox.
- When you step in fire, you only get burnt for a few seconds, then the status expires, even if you're still standing in flames.
- Some things make no sense to dodge. If a slime falls on you from the sky, you take no damage if you jump right before he lands. Also, standing on some furniture considers you high enough to dodge enemy projectiles, even though these same projectiles seem to pass above the object you stand on, and would hit you if you were on the ground.
- Any unexplored room next to those that you explored is revealed on the minimap, along with its type of content (you can know what kind of event is in a locked room without unlocking it).
- If you spam the "interact" key (E) at a NPC, it acts as a queue. Once their dialogue is closed, it will open again for the amount of times that you spammed the key at them.
- The level transition freezes you in place (and in the air if you were jumping) while moving your character to the next room.

Gostei! Bom jogo para passar o tempo e esvaziar a mente... pelo menos no começo
