first, AWESOME job dude! i can tell you've actually put alot of time and effort into making certain things work the way you want them too, like all the props having what looks like a mangled version that they switch too when they get hit to show youve hit it/ run it over. i LOVE the background skybox you have too it all so well done!! a couple things i think should be changed / added: after about 15 - 20 minutes of playing it gets kindve old tbh becuase you unlock that second area and its just the same exact thing over again, there should be more upgrades that change the way you play the game, maybe boosts? or jumps? or some sort of swinging thing or crusher you can add to the truck? idk something to make people want to grind for that next upgrade. another thing is, everytime it says "a new valuable material is coming!"... theres NOTHING that tells you what that material is, so i have no idea what im looking for and whether or not i got it or not, the valuable material should be highlighted, or it should say the item it is so i can look for that, or highlight the claw it comes out of idk something like that. REALLY awesome work though for real!!
