  • The first playtest of the game was done after level 1&2 was completed. 2 friends in Nicky's discord server joined the playtest, and a few other people watched the game play. Here are their suggestions:
    • Make a tutorial level and leave the enemies visible there;
    • Draw out the enemies' sightlines for the player;
    • Disconnect the enemies' alarm systems, so the player can kill them one by one;
    • Slow down the bullet speed.
  • All of the suggestions above made it into the final version of the game (or at least partially).


  • The second playtest happened before our presentation. About 5 of our classmates gave constructive criticism after playing the game:
    • The 4th stage's hidden enemies are amazing;
    • The scoring system is unecessary;
    • Lacks explaination of the detailed mechanics of attacks;
    • The vent doors should be both seeable before player's teleportation;
    • Make the dummy more interactive;
    • Decrease the difficulty of level 5.
  • All of the suggestions above were taken into consideration of our future development plans.


  • The third playtest was done after the presentation. About 5 of Nicky's friends joined the playtest, some of which have very little experience in platformer games. The following suggestions were received:
    • Decrease the overall difficulty;
    • Add plots and context;
    • Show the enemy's direction when they are not on the camera;
    • Debug on the ability, including stuns;
    • Decrease the time it takes for an enemy to die after being stabbed.
  • The suggestions above will be considered in future development.
