This was really fun to play! I really liked the art style with the goofy animations and fish with funny hats! I also like the absurdity of being able to reel in that giant squid! The game progresses really well, starting off really easy and ending as an almost bullet-hell! After a while I caught on to how each upgrade used a fish as a pole and a fish as bait, so I started looking for specific fish that looked like they could be a pole or bait. This game also captures the theme really well, and is very well-balanced! You did a great job!
Also I just realized that "Fishing Hell" rhymes with "Wishing Well". Probably not intentional but it's a cool coincidence.
