I (and the people I played with) believe that your game had an interesting concept, but not well executed. I give this 45 cows out of the herd of 100.
The most important thing when you create a tabletop is creating a clear rulebook. The reason being is that you don't come with the game, so you won't be there to explain the rules when they have a question or don't understand something. We felt that your rulebook was artificial complex do to your word choice and your sentence structure. I would find a way to make your rulebook easier to comprehend because if players cannot understand your rulebook, they'll struggle through the game at best. At worse, they won't play it. An idea to help might be to add pictures or have an example game in the rulebook. Have people read your rulebook too and ask for their thoughts. This way you get the view from a outside viewer.
The next thing I want to bring up is your scoring system. Truly, I thought it was a great idea. I have never seen it before. However, it too is very complex. I actually had to write a math equation to make it work, which a player shouldn't have to do. I would either change the system to make it simpler or find a way to explain your current system in a more effective so that the process it is easier for players to understand. Perhaps add a table for that does the math for them.
The final topic I want to discuss is card balance. When my group played the game, one of the players ended up with a large proportion of the "-1" cards in the deck. Because of this, she would play on the other players a lot which would cause the counts of the different colors in everyone else's deck to increase. This basically causes a score inflation in for everyone else in the game. I would add addition "+1" to your deck in order to reduce the chances of this occurring. You already have blank cards in your print outs, I'd start with those.
Again, we feeling your game has a very interesting concept. If you adjust those things I believe your game will be a lot better.
You did a good job with this game. Keep up it up and good luck. I hope to see more of your work.
Short but sweet! I will be releasing a play-through on it tomorrow (3:30 EST) on my YouTube channel. Needs more attention, I think it's a really cool game. I believe it just repeats, but please let me know if there's more to it!
