How Rube!
Nice puzzle game in the spirit of The Incredible Machine series from the 90s.
It does have a quite uneven difficulty curve, where about half of the levels are way too easy (like a prolonged tutorial), and later hits you with some quite illogical puzzles where you don't really use any skills you've picked up along the way, but instead just keeps throwing new, more intricate stuff at you.
All in all, the levels are always more fun than frustrating, but the first half of the game seems rather pointless and I wish the level progression was more inspired.
If someone held a crossbow -- tied to a 1 KG weight set to trigger once a basketball tipped over a domino brick -- to my head, I would give it 3 stars.
