The only upgrades you need are the bombs and the nail upgrade. Those two are enough to get your repairs done in plenty of time.
Great game. I didn't expect much from the gameplay, but it really worked.
ometimes you have to hire a specific new person. Play the levels you can until you've developed enough times to get the people you need.
It's not that long or hard a game, people.
These bet-on-racing type games need a lot of variety, and this one doesn't. The stamina and speed challenges are identical and easy to memorize, as are the step sequences during the race. If they can be randomized, even a little bit, it would make the game a lot more challenging. You don't want it to take 52 races (from never seeing the game before and skipping the instructions) to get to 50 wins. But it's a good concept. I'll give it another go if you upgrade it a bit.
Nice game engine, and excellent plans. Two recommendations:
one, make the off-track sand slow the cars down more than it does. There's virtually no incentive to stay on the track. and two, more levels please.
If a pop-up ad is going to appear multiple times in each level, in the middle of a battle, on purpose, then it doesn't matter if the game is any good.
If I want to get interrupted constantly while I'm trying to concentrate, I'll have kids. 1/5.
