suuuper awesome game. i just love the visuals, everything is so polished and thats probably what i enjoy most about any particular game. Like for example the rotating save icon, it just looks perfect. I need to learn how to accomplish that effect, is it just the RotSprite method (upscale > rotate > downscale)? anyway enough gushing about the details.
At the beginning i was kind of frustrated with the combination of slow movement + platforming. Before getting the feel for how to use the momentum to my advantage, i felt like i was spending too much of my time standing still, grappling, adjusting my length and swinging in order to make it to another spot, instead of grappling a few times and using momentum to get where i want. after going back to the beginning levels after beating it, the levels didn't feel as frustrating because i was used to the momentum. It felt like too much of a contrast between the 'slow, position-management' platforming and the 'fast momentum grappling' later. i feel like there could be a better way to handle this learning curve at the start, but im not sure how. Even the first jump was kind of weird, it took me a bit to even realize i could make it onto the next platform. the first two levels are pretty good, but im still not sure what the best method is to beat the end portion of the third level.
As for the controls, I was going to mention that i found myself mixing up jump and grapple a lot, and was going to suggest making jump be both actions, or at least having jump cancel the grapple. but i noticed you added that as an option and i enjoy it a lot more that way.
Is there any reason you can't reel in/out while while moving? I think that was what made me most annoyed about the grappling. you can reel while swinging with momentum, but only after letting go of the buttons. Also im curious as to why you chose 'up' to be extend and 'down' to be retract, i feel like it should be the other way around. Everything else felt nice though, the momentum is very good.
I think my favorite part was cheesing the red outlined block level by grappling the first block, letting it push me into the platform, and shooting me off to the right to skip half the stage. I wish there were more opportunities for me to do that again, that seemed like the only spot.
Also I figured out you can grapple at the ground and use the jumping effect to gain height from nothing:
not super helpful in most cases but still fun to do haha
anyway i can't wait to see where this project goes. the polish is absolutely my favorite part
