Dude, seriously, you've got a game with gamefeel and a lot of polish. You understand how a game needs to feel - and it feels GREAT to play your game <3 I could play it non-stop if there aws an endless mode
I just felt like maybe the level design could improve a bit - at least on the browser version, I couldn't see some of the grappling points, so some parts were super frustrating (one specially where you drop down a long shaft and there's spikes at the bottom - I bet that if I could see one of the grappling points before I fell haflway at full speed, it'd have been good, but... oh well). Also perhaps not the most innovative idea, but I like to think execution is a bigger part of game jams - andy ou've got that down to a pat. Well done!
