Still playing Iconoclasts.
Some technical niggles. It's missing a sense of growth or progression you get from the really good Metroidvanias. There're no health upgrades, no XP, no currency to get or merch to buy and no new movement abilities to unlock. You have your two starter weapons, each with a couple of story-mandated upgrades, and that's pretty much it. You'll never discover through exploration or intense puzzle solving anything that isn't a schematic for a tweak or the material to craft it. And frankly tweaks are kinda lame.
They're like the mods from SteamWorld Dig 2 and the charms from Hollow Knight: equip them to walk a little faster or get an extra hit, stuff like that. Except you can only equip 3 at a time (and never ever more than 3), and if you're like me you'll keep the same 3 tweaks on for the duration of the game (or at least 60% into it, which is where I am right now). Simply put the majority of them will ever be as useful as anything that lets you do stuff a little faster. And even then tweaks break when you get hit. You can farm 2 or 3 enemies to restore them, which isn't a big deal but it will definitely be constant one.
So as fun as exploring and doing the puzzles can be, that's somewhat mitigated knowing the reward will just be another crafting material to add to the pile to craft a tweak I will never equip. I'd like it better if you were able to increase the number of tweaks you can equip, and if they all didn't take up space equally, and if they wouldn't break as soon as a level one goomba brushes past me, and if the save statues would restore them like they already restore all your health.
Otherwise exploration is fun enough. I always like it when your abilities carry over across the three legs of combat, puzzle and traversal. Your wrench is good for hitting enemies, parrying projectiles, unlocking doors, charging machines, grappling across ziplines, swinging from platform to platform, etc. The gun feels more like a token addition to combat (it tends to self-aim so long as you're within 45 degrees of the target) but the bombs are fun to use in puzzle-solving, especially once they can carry electrical charges and you can detonate them at will.
