This is a really well done game for a first game! :) Congratulations in making your first game, I really liked the concept as an RPG fanatic~ It has rpg elements, and typing, which both I really like (yes I like typing HAHAHAH). You can definitely add on to this in the future, the structure looks fleshed out, you just need to work on certain areas to make it better ;)
Some points you may consider if you plan to work on this in the future! :
I think in terms of UI, you can perhaps zoom the camera out? I find myself scared of being lost in the map lol so I was not entirely sure where to go the whole time, so I checked everywhere HAHA, but also the text during battles at the bottom felt too big ? It might be because I'm full screened, but Unity's canvas can help you with that (although it is tricky sometimes!)
As a player, I was not sure about the power button at first, but when I tried it I realized what it does! It just was not obvious to me haha
You should add a sprint button to the robot, in case you plan to make the map bigger!

Overall, I really really liked what you have done, and it's your first game! I'm not really sugarcoating anything, but I'm really impressed and like the concept, I hope you consider making this a bigger game though! It's well structured already :)
