The grappling is a very cool idea here, sadly my mortal brain and finger coordination is not enough to swing as spider man around. I also do not fully enjoy momemntum based ground movement due ot stuff Great Uncle Pixel explain below me. One last thing, next time please do not use the white flash transition as on the web it is a very harsh thing to experience, and can be an epilepsy inducer if used too much. There are probably other transitions you can use there. Keep it in mind for next time.
Graphically the game looks lovely, has a neat style to it! Nothing not to like here. Music and sfx were great, well done on those!
Overall cool idea that could use some tuning here and there. Well done!
