Naiad is a beautiful and relaxing puzzle game. You’ll swim around and solve small environmental puzzles, like bringing the ducklings back to their mama duck or bringing the butterflies to a beautiful plant. No missable achievements, completion takes around 10 hours.
A cool picross/nonogram game in which you solve 3d puzzles. It has some very nice quality-of-life features like greying out solves parts and removing the number when removing the excessive blocks. No missable achievements and completion takes around 17 hours.
On Your Tail is a great game that reminds me of the Ace Attorney series combined with a bit of “Mastermind”. Completion takes around 30 to 40 hours. I expect this to lower once everything has been found and documented. It has no missable achievements.
Gacha Fever is a fun bullet heaven game that looks so colorful and has many things to unlock. Completion takes around 18h and the hardest achievement is to finish a run without moving.
What an amazing adventure puzzle game! It looks beautiful and will look better and better the further you get with restoring the areas. It has no missable achievements and takes around 10 to complete.
A challenging nonogram/picross puzzle game. The game is more difficult than other monogram puzzle games as it will not tell you when you make a mistake. No missable achievements and takes around 9 hours to complete.
Mythwrecked: Ambrosia Island is an amazing adventure game with so many QoL features. The game will tell you very clearly when you reach a point of no return and to save before that, so I would say it has no missable achievements unless you ignore that warning. Completion takes around 9 hours.
An interesting and fun spin on the bullet heaven/survivor genre with partly passive, partly active weapons. The game is quite challenging at the last few levels and I never felt overpowered. No missable achievements and completion takes around 22 hours.
Neva is a beautiful and emotional puzzle platformer. Bonus points for the fact that you can cuddle with the wolf. No missable achievements and completion takes around 4 to 5 hours.
Recycling Center Simulator is an addictive simulator game in which you clean up abandoned plots and buildings and sell/recycle the trash you find. It takes around 23 hours to complete and has no missable achievements. One achievement is very grindy.
