No, I really appreciate your feedback! It's all really helpful, I want to work hard to make this balanced and as enjoyable as possible as well.
I will have an update coming, hopefully in just a few days, where I will replace all of the SFX with custom sounds, instead of various sfx pack content, and lighting will be a major one that is reworked. And I'll check in on the sounds lingering, and any stray ones that may not be getting muted, thanks.

With the DPS what exactly do you mean? It does get tough to deal damage, even if you have all of the possible upgrades purchased. But skills that have been Mastered get a boost in their damage, so it's required to have a lot of them mastered to progress through higher levels. You may have already discovered that, but just case that's what you meant.
**Edit**
I believe I just realized what you meant - Once you've purchased all of the skills, the dps being converted into money is pointless since there is nothing else to buy.
What I think might be the confusing bit is I never directly stated that the goal is to get the bar to level 100, which will "defeat" it and effectively been the game. So what I will do is change the bar's level to read "1/100" or whatever the current level is, and I will explore the options of using money after all skill are purchased.

I will work with your other suggesting, and balance things out again. I already though of adding a slider for all settings that can be accessed with a right click on a button, so I will go ahead and implement that for all of them.
I'll post again on here, and a Devlog with all of the changes once I get them in - it will be a small update so it won't take too long to put together.
Thanks for playing, and for your feedback.
