Really creative idea for a physics / puzzle game! It did seem a little heavy on trail and error, but when every finally goes perfectly, it makes it all worth it! I would love to see this idea carried further, with more levels, hazards, and other creative level designs! I would suggest having an indicator telling the player when each of the hazards triggers, just to eliminate some of the grindy-ness. But other than that, very fun game! Each level added something new and unique, and they were all fun to play! Overall great stuff!
