Thank you for checking it out! I've gotten the sound effect feedback a few times but I am totally clueless on what it would take to do that.
Was the unlocking part fun or more of a chore? Also curious if you liked the permadeath. The original gave you infinite revives but would reset your score to 0 each time.
I am always motivated by achievement systems. Humans generally have an urge to complete things and achievement systems just use that fact to get them involved. And as a roguelike player I like the permadeath feature - of course!
Implementing sound effects in JavaScript is a little special, but not too complicated if you know how to do it. Just check the source-code of RunToTheStairs from its GitHub-page to see how I have done it. The sound-effects are all loaded as HTML-elements. Just look for the <audio>-tags in "index.html". Let us take the nitro-sound as an example, it is played by the following command:
document.getElementById('soundNitro').play();
It can be found in the file "player.js".
Unfortunately I do not have the skill to create music and sound-effects myself. Therefore I bought this sound-effects pack from Oryx Design Lab. Fortunately I found Dekkanoid a very talented musician from Australia to create some music for me. Check out this playlist to hear how versatile this guy is!
