Oh boy, where to begin!
Maybe I'll start from the visuals, which probably have to be the best part of this game! I really love the fact that the backgrounds and object are created from simple shapes, without many details, and in a brown-orange color palette. That gives this game industrialized look, especially with all the gears, levers, and other machinery. It fits the theme perfectly, and combined with all the post-processing effects and the smooth animations, it makes the game feel very polished, and finished!
Another good part about this game, are the sound effects and the music. The sound effects are fine, but the real kicker, is the music! It's good overall, fits the silliness of the game perfectly, has a hint of industrialization in it, and considering it was made for this game, I am amazed!
As to gameplay, well... It is a mixed bag for me. I did enjoy figuring out the solution to these levels, which sometimes require precise shots, that need specific angle, power, and even torque, to complete them, which make the game challenging, but fun to play! I also like the humor in this game: engineers grabbing other engineers (or what's left of them), exploding in the most ridiculous of situations, funny dialogues, and even funnier ragdoll physics!
However, there are few noticeable issues, that make it hard to play this game. These issues being: unpredictability of ragdoll's flight course, engineers exploding conditions being a complete wack, and poor optimization. Because of those reasons, some of the levels have been frustrating to play, and when there were too many giblets, my frame rate could go down to even 10 fps!
But besides those issues, this is a really great game! It does show a good production value, and overall, you've done a good job with this!
