Thank you for your feedback!
The fire spouts currently can't be disabled—only avoided. However, future updates will introduce a way to shut them off, similar to how electrical hazards can be disabled.
I'm glad you liked the voice acting! However, it's not final—most characters will receive entirely new, professional voiceovers in the full release.
As for the ammo issue, if your pistol reaches zero rounds, it will automatically generate a new charge after five seconds. So, you don’t need to worry about getting soft-locked due to running out of ammo.
Thanks for reporting the bug! That issue has already been fixed in update 0.3.1.
