The gameplay is really repetitive and not exactly entertaining. I constantly have to dig and go back to recharge. This would have been okay, if I had some incentive to actually dig somewhere other than just getting the diamond.
The game would have been lovely if it explained something about how to dig. I was just riding around for the first 10 minutes before figuring out that the robot can dig through things.
The game would have been a lot more better if I had a clear understanding of what I was actually collecting. All minerals too similar which makes it difficult to understand what exactly am I collecting. The game would have been much fun if I could use those materials I collected for something better.
I have no idea for how long I need to dig to reach the diamond, I gave up half way due to how boring the gameplay got at that point.
I hope you learned something from this jam
good luck.
