Here is a checklist of things I look for when reviewing a level. the links go to specific level reviews with those features.
- Does it make use of backdrop, decoration and asymmetry to make an attractive level?
- Does the level make use of ample checkpoints?
- Does the player have a clear idea what to do? Are there hints or jems to guide the player?
- Is there a clear critical path, or intended path for the player?
- Does the level scale up in difficulty?
- Are the puzzles and obstacles challenging without being overwhelming or frustrating?
- Does it make use of mechanics that are engaging or innovative?
- Does is highlight future challenges or objectives in a way that builds anticipation?
- Does it make the player feel smart or clever?
- Does the level use jems to provide two different routes, one for speed runners and one for score hunters?
