Tested on PC Web.
Good: Animations and smooth player movement.
Needs improvement: It's not clear what to do in this game. I just wandered around aimlessly and then get teleported for an unclear reason. It would be good to explain the goal to the player or do a tutorial.
Level-design is not bad but textures could be more fitting for levels. For example, the red tiles in the first level seem out of place and rock tiles are too dark.
Sound is missing entirely.
