Great concept and implementation! Nice level design too : ) 
Thanks for including a volume option! I turned it down and really enjoyed the music!  

Fun Game! I enjoyed playing it! The levels very super hard for me but It was fun trying to figure out how to win the level.

Nice to try to learn and progress with the game. I found the music (like my own game) a little loud and on a short loop when all concentration is needed for the jump controls. It's good to hear about hotbox tweaks and it was neat to have a really hard mode which definitely lives up to the name!

Bloody hell this game was difficult!

I boldly went ahead to try this game without going through the tutorial first, safe to say thats a lesson learnt.

After my initial incompetence, and when I learned how to play the game, I must admit - masterpiece.

Such a simple looking game but with so much potential. Would seriously enjoy playing more of this if it was to continue in development.

Great job!

Yea this game is fun. I love games that are difficult by skill alone like this. I only have one gripe. I like how the swing has a lasting effect afterwards, but I think it lags a little too much in the beginning. With that tightened up, it's perfect for me. 

I beat the normal mode but definitely could not get passed the first level of hard mode. That's for another day.

SUPER neat concept and I love it! It's a bit difficult to get the timings right but once you start to get into the swing of things it's super fun. I can definitely see this being a bigger game. I also love the 1-bit style! One thing I noticed however was that the area between the player's legs wasn't actually transparent-- I'm not sure if that was on purpose, but I think it's worth saying. Other than that, super good game! If you have the time, I'd appreciate it if you also played my game!

I got some serious Hollow Knight pogo vibes from this game lol.

This idea is genius. I love how you incorporated the "There and Back" and "Collectibles" theme into the actual gameplay itself. The gameplay is challenging but super rewarding once you beat each level, and it's highly addictive as well.  I do think the swinging hitboxes should be a little bigger though - maybe have them cover more of the player's body. Other than that though, this is a fantastic game!

Very cool game! Once I figured it out, I loved it. Tutorial is definitely a must play on this one. Incredibly difficult but the restart is so fast that it doesn't really bother me much. I could see this being a celeste like puzzle platformer and really doing it well!

Took me a while to understand how to play the game, but once i got it, i thought it was a really nice idea. Something felt off with the controls though and im not 100% sure what it was, could just be that im not used to playing with keyboard only. I also wish if i let go of the jump, it'd start going down almost immediately for more control. The art style looked great, music was alright and the idea was cool, overall really good! Nice work :) Oh and i also appreciate the volume control in the settings.

At first I didn't understand I was trying to collect the coins and get back to the same door (kept end up in box with a <3 in it and had to restart). Once I realized what was going on I had a BLAST. As someone who loves hard platformers like Meat Boy this hit the right notes. 
The hitboxes for squares and coins was super unforgiving, but I don't think that's necessarily a bad thing. Some will love it others will hate it. I was able to complete normal mode, but had to give up on stage 1 hard mode haha. Could maybe add a button to zoom out and see the whole stage to know what you're up against, but that all depends how much you want to player to discover on their own. Overall well done, thoroughly enjoyed playing this one. 

Really loved your implementation of the theme! Had alot of fun playing it.

This game was hands down one of my favorite platforming submissions. This game had hard shovel knight vibes. Though it took a lot of time to pass some levels I got pretty far. Art was simple yet fitting and the music (while a little repetitive) fit the atmosphere well. good submission!

Super fun little game, but also super unforgiving (which the quick restarts did alleviate some).

The pushing yourself was a cool mechanic, but with the quick response time required I found myself slipping trying to find the right button to press. As Sephta mentioned maybe using the mouse would make it a little easier.

With a little polish and tweaking I could see myself playing a bunch of this.
