I really enjoyed it! Unique mechanic with having to purchase the safety net's advancement through the stage. I like how it evolved from a mining game at first and ramped up to be more action-packed as it went on. Gameplay was well-polished and engaging.
The sound effects got a little repetitive. Some variation there could help. Also could have used some screen shake on hits though that's more of a personal preference thing.
I did a playthrough of it for my YouTube channel: https://youtu.be/w4rEjU_kc-Q
