好玩，不过虽然文字信息不是很重要，但是还是要说如果有中文就好了

A very good and satisfying ice gym game, which is a rare surprise :O A really excellent metroidvania-adjacent slid-y sokoban-y game, with many great ideas, interesting mechanical interactions, and tough levels. I very much recommend if you're the sort of person that likes large puzzle games with meta-puzzles, but not overly obtuse secrets, it's one of the best of 2025.

With that overall review, I I have a few critical comments which you should not take to mean you should not play this game, but perhaps to show that I think it's in a high tier of puzzle game and can take the kind of criticism you'd apply to the best puzzle games out there. (Mild mechanical spoilers below).

1. It feels like some of the interactions between mechanics originate from the designer just having some "resolution order" for the mechanics when they first experimented with it, and then being like "huh, that's weird" and sticking with it. But some of these choices are not that interesting or useful beyond perhaps being unexpected; they're just kind one arbitrary choice of that resolution order. One example that stuck out to me as both weird and actually kind of boring was the interaction between the rocket and the magnet, which gets used once or twice but isn't that different from just no rocket and a magnet. These types of situations feel a bit like "metroidvania filler" of these interactions needing to exist, but there not being anything all that interesting you could do with it. There are one or two levels which are just "spot one new interaction that will then never be used again", which I think the game could just cut.
2. Some of the levels still have a lot of regular sliding puzzle set-up (that I'm not all that great at) to get to a mechanical idea/interaction that is not that hard to spot. Some of these maneuvers are quite hard to work backwards through, which is what you normally want to do with sliding puzzle games, and feels a bit brute-forcey. This content can feel like "sliding puzzle filler", that I sometimes just don't want to do. I think that many games I enjoy have similar things of just "putting things in the right starting point" though, so not a unique problem for a thinky puzzle. I do feel like Headlong Hunt avoided this stuff a bit more, within the same genre, and is consequently easier. I think this game would not suffer from cutting some sliding and therefore being easier.
3. More of a comment than a criticism, but the recursion component is a bit less "recursion" than Recursed or Parabox: it's mostly about setting up the level inputs correctly by replaying it. This is a function of levels themselves not being objects you can move up and down the recursion stack. I'm glad the game did not get the name slicursion despite having a recursion component, or this would bug me a little more. Replaying the same levels with different set-up is one of the games best parts though!

Again, overall very good though, and will be working on getting as close to 100% as I can :))
