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.

  • *exits Unity after staring at scene for 5 seconds*
    I like using checkvist.com to break down a project. It's a to-do list, but you can zoom into subtasks which can be 'focused' into and appear as its own master list... You can break things down infinitely in a clean way. Source: over 3 years ago
  • Frequent loss of keyboard focus - expected?
    Thanks, yes I can see it's tricky. An outcome of Logseq's ambition I suppose. My primary tool for this kind of thing is Checkvist which is simpler but ergonomically very elegant and predictable. I'm looking at Logseq for more ramified topic notes, but I don't think it can replace Checkvist yet for the rapid-fire stuff (todos, quick capture etc). The ambition and achievement in Logseq to date is nonetheless... Source: over 3 years ago
  • Outliner + UpNote
    You might check out Checkvist. Simply link from an UpNote note to there for certain lists and you're done. Source: over 3 years ago
  • Show HN: I Made a Todo List for Developer Power Users [video]
    This reminds me of https://checkvist.com, which I hope would be used more. It's actually a great replacement for Trello or any other kind of board for smaller projects. - Source: Hacker News / over 3 years ago
  • Looking for a good Bookmark manager
    I use an online outliner Checkvist for my bookmarks as well as notes. It has all the organization features you mentioned and way more. It also has Chrome and Firefox extensions for making bookmarks. It's especially good if you're a keyboard user. Source: over 3 years ago
