I thought at first that I've played the first part a few years ago. Then I found out that the game I thought was the first part of this is a completely different game (but also made in RPG Maker) - Berathen: Spirit Detective.
Full howto for "destroy 40 objects" achievement: Cones and bananas don't count. There are 45 fences total so if AI destroys too many of them before you, restart the race. Drifting during first lap is bad, especially before the big fence roadblock which you need to destroy almost completely by yourself and still get to the next big curve with fences ahead of the AI.
Fiddletink: When you get knocked down, just press spacebar to stand up. You can recover from knockdown even while you're still flying. There's even a skill (Transcendence/Rising Counter, middle row, right column) which allows you to swipe halfway across the screen right after you get up from the ground.
This game has really serious performance issues to the point where controls get unresponsive on my machine (Intel Core i5, 4GB RAM). Seriously, system monitor says that Flash process takes 130% CPU time when I move and the delay between pressing a key and the command actually happening can take over half a secon! Games of this kind written in C could run smoothly on Pentium 90 almost 20 years ago so how come this game can have serious performance issues today on a machine that's a thousand times more powerful?
One thing that would make this game even better: get rid of edge scrolling and instead use absolute position scrolling (calculate the relative position of mouse from center of the screen, multiply by scene-size to screen-size ratio and shift the view by the resulting vector). Edge scrolling doesn't make first person shooters more challenging, it makes them frustrating.
Two things that would be nice:
1) When you open a workshop interface, you should see the number of each item in stock without having to select it for production.
2) There should be some indication when one of your workshops completes its task. Preferably a clickable one that will take you to the workshop's interface.
