Fun game! The music was awesome, so catchy it's still grooving in my head (unfortunately I can only rate up to 5). The 3d models (especially the dog, he's a good boy) and the sound effects were very nice and fit very well in the fun atmosphere.
My main issue is that I believe the gameplay is missing some polish. I don't know if its the dog that's too slow, the bark range, or the grandpas giving up on jogging to early, but half of the time I try to do something smart, I end up creating more traffic, its rather frustrating. So I have found another solution: STOP TRAFFIC COMPLETELY! And currently, I feel that it is by far the best strategy, just put the kind doggo in front of a car right after it spawns, and stop the lane for all of eternity. The car only honks once, so you can just stand there (and do a stare battle with the driver?) and look at the hoomans managing there life without you. There is still a second lane in the second level, with some cars, but I had a better score this way that trying to be play properly.
I still won with a margin the second time, so I really don't feel the game is too hard when playing normally, just that there is an incentive missing to push you in a more interesting strategy. And not just multiple honks to discourage you from blocking lanes, but a way to clearly play better, to anticipate cars, etc... It's unfortunate because I found the idea very creative, and I'm sure with slightly more tweaking it would have been much better. Maybe with more visibility for when cars are coming? With timers / traffic light indicators?
Well, I seem to be the only one nit picking, so its probably just me.
This issue could also probably have been solved with more levels, with more complexity, (and more lanes, so you can't stop them all), where you really have to think of a strategy to pass the level. (But I guess you never have enough time during a jam...)
I also notices some tiny bugs: If your dog runs too far top in the first level, and tries to come back, he can't: He has just entered a parallel universe just 10cm bellow the real one, and can't will never be petted again!... (or until the second level.) Sometimes cars stop if you run behind them. And there is a loop for the winning jingle.
Still very cool game! I might have overdone it and detailed to much my issue, so it might seem like I didn't enjoy it, but its actually because I got too invested and frustrated by the incomplete potential. ;) Anyway, great job for a first collaboration.
