It's unlikely, but perhaps possible, that you had a 100% save which might now be at about 99% or so if there is a room you somehow avoided while collecting everything.

v1.0.4 Patch

New Features

  • Achievements are here! There are 47 achievements (8 of which are hidden) for players to unlock. If you've already been playing the game, or have even finished, you can still unlock achievements by simply loading your save slot. As soon as you load a save slot in, it will get your achievements and stats up to date based on the information that was already being tracked in your save files. There are a couple of achievements that we were not tracking data properly for, so these won't unlock automatically: Talk to Wilfred with the Frog PJs on, Defeat 50 enemies at Max Rank, and Defeat an Enemy with a Bubbled Projectile. All 44 other achievements should unlock automatically if you had already met the criteria for them.

  • Made it impossible to get up to the Cliffside Summit using Frog PJs.

Known Issues

I was almost entirely focused on achievements for this build, so existing issues still remain, and I have a better sense of what's happening with some of the issues players have brought to my attention:

  • There is a bug which can cause the game to get into a bad state and cause a drop in performance. If you encounter performance suddenly being noticeably worse, you can simply touch a bed, choose Save and Quit, and relaunch. You won't lose any progress and that should fix the issue. While playing extensively to test Achievements, I started to get a better sense of how and why this is happening, but it will take more work to get it solved.

  • Traversal stutters which were improved in 1.0.3 still remain. As with before, you typically won't notice these, but on a Steam Deck or in other scenarios they become more noticeable. These will get fixed as we focus more on performance optimizations necessary for the Switch port.

  • Some players are reporting an issue with the game getting the permissions needed for the save files, which results in the game hanging for some time before it corrects itself. This one is very difficult to replicate on my hardware, so if you're seeing this issue, please report it in the Discord server or Steam community forums!

  • Bon-Bon dialogue reads as if her house is advanced to the next step after you donate candy, even though it won't actually advance until you leave and come back.

  • Bon-Bon's secret dialogue about her amulet is slightly incorrect/out of date in some scenarios.

  • The Knightmare Armor boss can be soft-locked if one of its gems gets released into a wall.

  • The …? minimap icon sometimes remains in place after exploring a room and renders on top of the room.

  • Sometimes when going through a camera transition, the camera will clip through a camera collider and peek into an adjacent screen. This is similar to the bug that was fixed in this patch, but importantly the camera collider is actually there, so Nemo can't escape and if the camera comes back fully into the room that it should be in, it won't escape again.

Planned Work

Next up, I'll be tackling the in-game music player. As with the Achievements, I'll probably focus solely on that to get it done quickly, and once shipped, I'll turn my attention back to the hunting down these more persistent issues that have continued to pop up.

  • In-Game Music Player

  • More Bug Fixes

  • Localization Planning
