Thanks for the feedback!
The music:
So the funny thing about the sound the two sound tracks that I wrote for Callais is that the where supposed to be swapped. In other words, I wrote the title theme to be in game and the in game track for the title screen lol. They were also both created to be looped but the developers were working on other things so it just didn't happen in time for the deadline. Which I totally understand and they made sure to let me know that there will be updates that fix these and other issues. I'm still happy and proud of the way it turned out! If i would have known they were going to switch them, i would have made that main theme WAY shorter and spent more time on the marimba piece. That sound btw is the marimba sound that comes with Garageband! So you are correct! In fact, everything you heard in both songs either came from the stock Garageband sounds, free plugins or a mixture of both. Also for reference I listened to the "Ori and the silent forest" soundtrack on repeat for practically 48 hours.

The sounds:
As far as the sound goes, I didn't see any art the whole time so I was working purely off of quick descriptions through a discord chat. Descriptions like: "mystic" and "rock guardian." So my brain immediately went to something big, like a rock giant that shakes the ground when he walks. To achieve this i went through some old foot steps I had and to add the weight I layered a mix of like 5 different presets on a free audio plugin: https://tal-software.com/products/tal-noisemaker. I then added a snare drum from a different free plugin: https://obxd.wordpress.com/ to give it a good punch. However it didn't really sound 'earthy' enough so thats when i added the crackling that you are talking about. I was going for the sounds of loose rocks/dust/gravel like sounds so on some of the tracks I added another free plugin: https://www.izotope.com/en/products/create-and-design/vinyl.html and cranked up the dust and detune features that it has to give them that extra detail. So sense it is vinyl crackling, I see where your concern came from and assure you your speakers are fine! For the future updates of the game i'll try a few different/more natural methods like fire crackling or actual dust and dirt!
Your game:
I really enjoyed it! I especially loved the title music! whatever synth you used for the bass gave me chills and I have to know what it is! The game theme I think was solid but I would have liked it if it went on for a bit longer (maybe a minute or so) before looping. Also, i think maybe a faster tempo or a more energized beat could be really beneficial during gameplay and perhaps even drive up the anxiety if that is what you are going for. The sounds were solid and I feel like they all stayed within the theme of the game very well! I especially like how you could hear a bullet/laser before you could see it in some cases. The only thing that threw me off was the fact that the energy bar didn't make a sound when it went down. I was pushing boxes around like crazy until i looked and saw that it drained my health. I think if you added a subtle sound that let the player know when they are draining their health it would help with this!
Over all great job, keep it up and thank you again for the feedback! You definitely gave me some things to think about!
