Thank you for the constructive feedback! :D
oh yeah, you're right - to be absolutely honest, we never thought that so many people would play it, so it's kinda embarrassing that we didn't change the SFX or make another recording :'D and we couldn't believe that nobody commented on it until now lol. So, we really appreciate you mentioning this and are considering to polish the audio and other stuff for an after-jam update! and thanks again! :)
