Level Devil features and specs

  • Simple and Addictive Gameplay
    Level Devil features straightforward platformer mechanics that are easy to pick up but hard to master, making it highly addictive for players of all skill levels.
  • Unpredictable Challenges
    The game constantly surprises players with unexpected traps, shifting floors, and moving obstacles that keep the gameplay fresh and exciting throughout each level.
  • Free to Play
    Level Devil is accessible as a free browser-based game, meaning anyone can play it without needing to download software or pay for access.
  • Minimalist Design
    The clean, minimalist art style and simple controls make the game visually appealing and easy to understand without cluttered interfaces or overwhelming graphics.
  • High Replayability
    The difficulty and unpredictable nature of the traps encourage players to replay levels multiple times, providing a satisfying sense of accomplishment when finally completing a tough stage.

Possible disadvantages of Level Devil

  • Extremely Frustrating Difficulty
    The game's reliance on surprise traps and sudden deaths can feel unfair, leading to significant frustration especially for players who prefer skill-based challenges over trial-and-error gameplay.
  • Repetitive Mechanics
    Despite the surprise elements, the core gameplay loop of running, jumping, and dodging traps can become repetitive over extended play sessions with limited variety in mechanics.
  • Limited Content Depth
    As a simple browser game, Level Devil lacks the depth of a full platformer โ€” there are no storylines, character progression, or complex level design elements to keep players engaged long-term.
  • Trial-and-Error Design
    Many traps are nearly impossible to avoid on a first attempt, meaning success often depends on memorization rather than genuine skill, which can feel cheap and unsatisfying.
  • No Save or Progress System
    The game may lack robust save or checkpoint systems, meaning players can lose significant progress and have to redo sections they have already completed, adding to the frustration factor.

  • Found out Iโ€™m pregnant and itโ€™s already too late.
    There are some, I've seen Periodical on F-Droid before, but I saw now there's another one called drip. Probably more out there, but both of those are also available on Google Play for people who aren't FOSS nerds like me. Source: over 4 years ago
  • I'm looking for a self-hosted period tracker / pregnancy planner for my wife.
    Do you really need it hosted? Is a private app enough? For example, on Android, there's Periodical and I think it doesn't even have the internet access permission. Source: over 4 years ago
  • Everything is fine.
    If you have an Android device, Periodical is a simple tracking app that does not have Internet permission so it literally cannot share your data. You can back up its data to a text file to restore if need be, and keep that backup off your device. However, if your phone backs itself up to "the cloud" you could still incriminate yourself.
