This remainds me of a game I play (need for speed hot pursuit, a really old version with similair graphics!)! Your game is very nice, although i think you should change the steering a littlebit, because everytime my car is spinning
Just focus on upgrading steering and resistance (both tires and car), because that is the main problem!
From time to time upgrade boost, accel and fuel!
ALWAYS drive defensive (except maybe the first 2 races) and NEVER make pitstops (except maybe for refuelling). pitstops take away most time! By driving defensive you will get less damage, and since all the opponent cars make some pitstops you're always faster! And by driving defensive you will get less damage!
Also DON"T pitstop if you have chosen the wrong tires, because changing tires takes REALLY LONG, no matter how much you upgrade your pit team!
Oh and of course never upgrade your pit team, you don't need them!
And by choosing driver, always choose the driver which can upgrade the maximum steering!
oops and I forgot one other thing, make the doors visible, like make them another colour, so when you move the switch you can see the door "inside" the wall!
Oh, and I forgot to say, but make the collectable items something diffrent, like a note from a diary or from someone that needs help!? Maybe add something like that! And make them readable/usable, so people can come more into the game!
Nice game, but there are not enough "puzzles" now it is only searching for the door switch! And on the second level I could find the switch but I didn't find the door! :(
And one more problem I had was the torch, it didn't really light up the way far enough to know where I am going! Maybe that was why I got lost!
Maybe make some recognision points on the levels, so people can remind themselfes a littlebit where they came from and where that door was!!! For example by making the wall another colour, or add some torches on the walls! Or some other stuff, I don't know!
One last thing, I was expecting some ceartures to fight against, but that didn't happen, maybe add some creatures, or focus on making more diffrent puzzles!
This game reminds me a very little bit of Prince Of Persia and I mean maybe you should make some sort of puzzles like in Prince Of Persia (If you know that game?!)
Anyway it is a 3/5 now for me!
That new crafting (combining cards, the nexus) is pretty useless! I can't even find one match of 6 cards, and it would take me ages to find a comination/combo! :(
there is one point on the map (when on the beach/sand), where i can drive underneath the buildings, also fun, but i think that's a mistake, I don't really know how to point where on the map it is, but the normal street/sidewalk and buildings are placed too high!
when I reach 4 stars (or more) then it get's a littlebit too impossible to get customers with 4 stars, and then the rating goes down :( (it even goes into the -), this is really a bad balance!!! And this makes it impossible to ever win this game!
