Very nice game and fun concept. I love how the main menu is your base and how it's ugraded after completing levels! The only things i think could get improved is to have better feedback for when your hook is stuck on goo and how to escape it (like make it covered on goo). Also some better feedback for when your line get's caught by spikes. In the 2nd level it took me a few tries until I realized why I was dying. And the last level was way too hard for me XD
