I can see what you were going for and it definitly works a mechanic but it fell a bit flat for me. I found it frustrating that I woud get a good swing going and then enlarge my fist only to lose all momentum. With how much the first slows and how short the enlarging lasts its as if you expected the first to always be still in one place when it was made bigger. That is defiitely not what felt intuitive, I want to get a good swing going and then inflate at the last moment to barrel into enemies in a glorious display of destruction. 
I'm really glad you had sound sttiinngs, the in-game music was great but I found the menu music a bit repetetive. Your inclusion of a screen shake toggle was very cool accessibility although I kept my screnshake on.
I would also fix your game dimensions in your page. At the moment the game size you have set is wide and short which makes the game very small on the screen where fullscreen is basically mandetory. If you've built your game for 1920x1080 then I would rcommend setting the screen size on itch to 1280x720. That will give you the right aspect ratio and fit nicely on the screen without being so small. 
All in all this is a well made game with some great thought put into options and polish, but wasn't fully to my taste. Well done. 
(edit: spelling)

Wow, it's perfect! Such a fun mechanic :D

I really like how you have to use the fist to fight the enemies which adds a lot of challenges and fun to the gameplay. The game felt polished and really good for a game jam. I wonder how you guys were so quick with it! The art was also cute and nicely done!

Getting used to the fist was a bit tricky for me, but it's also so satisfying when you master it and land big hits around. Well made and polished game!

This game is very well done for the time, the online scoreboard, the art, anything just felt very well done.  At first it felt like an ice level, which at times was frustrating, Thou the combos more then made up for it. 

Oh you sly dog, you, adding a scoreboard. You got me monologuing! And by monologuing I mean playing for like half an hour. I love this!

Great concept and idea! Really original and fits well with the jam theme.
Well done!

Wow, I sucked really hard at first, but with a little bit of time I get used to the controls and it became really fun and addictive. Well done! :)

Really cool and unique gameplay, love the style as well!

this is quite the juicy game, I must say. VERY satisfying!!

I've played another game that does the same thing, and i have to say this game does it much better, besides the physics that work better here the addition of the fist size increase really makes this work

you can almost string together attacks using the return velocity of the fist growth

i don't really like that the game is timed, it can add some unneeded stress, although it was well implemented so it didn't bother me

my main issue is kind of the same as the other game that did this, the fist mechanic is just a bit awkward and can make for frustrating moments, here specifically enemies can get trapped between you and the fist and sometimes miss enemies entirely

Nice simple game, my only complaint is that the fist feels too random, so it's hard to use it properly, but I do like the feel when it does hit.

Really nice game, well done! It reminds me of Hammerfight. The how to play at the beginning is very handy and has a good lay-out that doesn't feel like a wall of text. Getting the fist to hit just right and get two enemies in one feels very satisfying.

And I agree with Mrjackphil, thank you for listing your used plugins, very helpful. :D

I do not have complaints, just that i suck at the game, but well great game!

Really like this one, will play again!
