You descend a dungeon where each enemy has a unique set of abilities and string difficulty. In combat you are presented with a string, make no errors and only you hit, run out of time and both you and the enemy take damage, mess it up and only the enemy hits. How fast you recall it affects the run grade.
Built in React, with Phaser and Three.js as the 2D and 3D renderers you can toggle between.
The graphics are CC0 DCSS sprite-set, so I can't take any credit for it and I am quite grateful that I found it.
Happy to answer any questions and will appreciate any feedback. Thanks!
