Delightful physics game

Only thing lacking is an understanding of how stars are achieved. If it’s based on items used, assign them each a dollar value (eg, wheels are $100) and then set a budget for each level (eg, $500 spent = 3 stars, $650 = 2 stars, etc.). If it’s based on time, tell the user what to strive for (eg, 10 sec or less = 3 stars). Because right now I have now idea why I’m getting 1 star on some and 3 stars on others.

Also - users need the ability to replay the intro / how-to. (I don’t know the difference between the solid and dashed lines, and would like to go back and view the demo again.)

Great game!

This game is great. Basically a direct remake of fantastic contraption and that is exactly what I was wanting, as I used to play that game all the time. The visual design of the game is a nice touch, and I haven't run in to any issues so far. I appreciate that there is a leaderboard, however in future the ability to see and play out other people's uploaded designs would be awesome. Also the ability to make your own maps to play out yourself or to upload for others to try out would also really take this game to the next level.

Cool, but gets difficult fast

Loved the ability I had to just build things I thought might work, and figure out solutions by trial and error. Once you get a few techniques down, it’s fun to fool around to get your best time. However, towards the end of world 2, the puzzles seem nearly impossible. I wish there were more “medium” difficulty puzzles. Also, maybe a way to skip a level, and not too reliant on stars to unlock new worlds. I want to see what other levels you have, but hit a wall…
