Got back into this game recently and the levels were suddenly got quite a bit more challenging and fun than I remembered the earlier ones being, impressed with them so far now. I'm still early in the game but it's clearly worth it. Good level design, good confidence in the game's own controls and mechanics leading the dev to reuse what works and what would be a bit gimmicky in other games but works here as a solid regular thing (block breaking, carving through lots of blocks).
