It's interesting you say the sound effects are what you would expect of a commercial match-3 game, because the sound effects were heavily inspired by Bejeweled 3. I find the sound effects of this game to be intense and satisfying, something that I tried to replicate for Untergetaucht. However, I noticed that the in-game audio mixing diminished the impact of those sounds significantly, and maybe they would be more satisfying if we had more time to work on that.
