They could definitely use some refinement sure, but what you have makes sense SFX wise. I don't think I was scratching my head at any of them and the music started to get repetitive but it really reminded me of this trilogy of adventure games on the NES Shadowgate, DejaVu, and Uninvited. Catchy and short tunes so I really enjoyed it from that angle :) so definitely don't be too harsh or anything! It's all still good in my opinion!
