Just one achievement: Beat the game without dying.

I used a guide showing an easy way to earn this achievement.

Replayed the game just for clearing two new rooms and few miscellaneous achievements.

Played it again just once for one new achievement.

The latest patch added the new level and achievements.

✅ Level 3 beaten
🏆 All achievements earned.

Returned

I returned to play just for newer achievements that was added by latest patch three months ago.

Returned just for one new achievement. Just simply play for a bit and lose.

🏆 All achievements earned (42 out of 42 earned)

Update: (06/14/24)
Used to have an additional achievement by patch, but the developer removed it for whatever the reason. As a result, the 'mastered' tag has moved back to the previous date.

Returned

Returned for two new achievements.

🏆 All achievements earned (19 out of 19 earned)

Returned to play after looking at the news about the latest patch. Apparently, the achievements are working now.

Good news for Steam Deck players: your achievements progress actually works in offline mode!

Update: (04/22)
Sadly, your achievements progress can't carry over between desktop and Steam Deck. For instance, if you have 5,000 enemy destroyed and you move to Steam Deck, it goes to 0 due to the game thinks you're playing on different system.

Achievement earned.

Used to gotten all of the achievements before the latest patch (Jul. 21st, 2022).

Had to use my 8bitdo Pro 2 controller to turbo the spawning in order to lose repeatedly. This is all due to glitch coming from developer's shoddy coding.
