Very nice game! It sure was a challenging game but the chill music and fast respawn saved my sanity. I really liked the game and it worked very nicely except the intro video was completely black. One thing I would've liked was to be able to use the grappling hook when you jumped, but it worked fine without that as well :D
Overall a very fun and enjoyable game!
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
