Getting 100% was... entertaining, and scratched that clean_map itch us completionists get.

approximate amount of time to 100%: 20-30hours
Estimated achievement difficulty: 7/10
Minimum number of playthroughs needed: 1
Multiplayer achievements: No.
Missable achievements: No.
Point of no return: No. After the game's ending you can return and explore.
Grinding Achievements: Not really, Maybe "reach level 100" if you skip a lot of fights.
DLC-Only achievements: No.
Time-gated achievements: No.
Speed-run achievements: No.
RNG-achievements: No.
Does difficulty affect achievements: No choice.
Is there a good guide available: An excelent set of maps by @Demajen for missing pickups.
First achievement unlock: Immediately after Beating the first boss.

I recommend this game as a solid metroidvania. Doing everything right.
If I were to make a recommendation it would be to just enjoy the game and take your time.
Nothing is missable, there are no hard difficulty walls and everything comes down to pattern.
In addition there's no penalty for dying except time wasted.

I really enjoyed this one. Hope you will too.
