Got around 204 Plaps before calling it quits, good game overall. I could see a future update where the game would get Fullscreen and naturally walking NPCs (when not spotted) could come into play eventually.
Only complaint is the screen being pushed up when locked in an animation which could leave the player vulnerable from surprises underneath the player vision which I'm sure an Fullscreen and unlocked view when in animation would help a lot. (But that's where I would see the game becoming easy then, so to balance it out I could see a potential NPCs patrolling being a thing.)
Great job on the game, Guan Zillan!
