Thanks! Yeah, polishing is one of my favourite things to do in game dev. Adding some cool effects and shaders and so on. That along with the initial few hours of prototyping are my favourite bits really. Sadly indeed it is quite often overlooked in jam games but in a longer jam like this it really should be a given. In the grand scheme of things it really doesn't take that much time to add some effects, small animations, screen shake etc yet they really do a lot to help sell the look of the game and make it feel that much more alive, even with humble art assets.
Yeah same, I usually do 48 hour jams too but recently I've really started to enjoy these longer jams more as they aren't so strict timing wise having to dedicate pretty much whole weekend on it and can just semi-casually work few hours per day and even keeping some days off as needed. They also give much more freedom to experiment with different stuff.
