I like the game a lot but it loses a lot of the challenge once you reach "freeplay" mode. Rather than a constantly expanding item list it reduces to scraping everything but your blueprint factory and building whatever random 2-layer object it tells you, wash, repeat.
Level 18 was ragequit city before the update for me. Still annoying but it's doable. I enjoyed Rob's other recent games more as they involved more logic than reaction time that this one.
Concept is good but it would have been been better with about 10 less levels and an greater increase in difficulty. It was feeling grindy and I was starting to lose interest around level 30.
Too many levels... Got bored around level 70, and i see from the comments there are over 100 levels. Would be better to have fewer levels but ramp up the difficulty quicker.
Rating updated to 3, Would have been 5 if all the levels had been included at the start, voted 4 initially since it was submitted missing half the game (last 5 levels + speedrun mode).
A small hint: You have to kick one of the lava balls against the partially melted movable ice block.
