The sequel is great so far! I lot more to do than the first, and I love the added health, etc.
The maps are nice and big, there are lots of cars. I don't totally understand all the power ups but, I'm sure I will with time.
One thing I would love to see in the maps that I think would be cool is tunnels or hidden caves that you have to discover on your own.
I think the price of the cars are reasonable, but I've noticed that you gain money quite fast. I don't know if it will be necessary to increase the cost of new vehicles but I would suggest to increase the cost to unlock a new map only because I can see people quickly unlocking everything and loosing interest in the game.
Concerning the turbo boost button, I would suggest adding variety for each vehicle. Faster cars seem to fast for the cops with the boost. So I would suggest that you would increase the recharge time for faster vehicles, and for slower cars, it could be a weaker boost with a shorter recharge time. Just some balancing suggestions to make it more challenging.
I think it would be also cool to be able to switch cars during the game as well. This doesn't necessarily have to be the cars you have previously unlocked but it could be like a hidden car in the map or a location we have to reach (the tasks/missions) were we switch into that car and it is a better car that we have for a limited time, which could be for one mission for example. This is not a necessity or a fix but I would love to see this because it would make the game more fun.
Also, I feel like the guns are pretty powerful even at the start. I can survive with the weakest gun for quite a while and end up dying because of driving, messing around, or boredom due to ease. I would suggest to weaken the guns overall to add more challenge to the game but also keep more powerful ones to add more incentive and fun. Not a huge thing but I think it would make it better.
Finally, what I really loved about the first game was that we had the option to play in third and first person. I understand that it requires a lot of work to make it possible (especially with the increased complexity of the second game); however, I would, and I am sure everyone else would, love to see that introduced in the second game. I believe this is what makes Pako different from other top-down car/racing games. I really encourage you guys to implement this into the sequel. It would both add a more personal, cool perspective as well as aid to navigating the map and make it more fun.
Other than those things I believe this sequel is excellent! Keep the updates coming and good job guys!
