Glad you liked it! The main idea behind this game was to make it something that the player would be able to understand by themselves in a few runs, instead of clearing it in the first run, happy to hear that experience translated well to you! The tutorial, I'll admit, was shoehorned into it because I wanted to give the player a chance to do a test run before getting into the main game and programming battle events in the engine is a bit stiff so I had to resort to text, all that is to say there's a reason I made it optional hahaha.
The machine that shows the enemies is supposed to be like a levitating monitor, though I do need to rework its look to be something more high-tech looking... The main story as well as other side quests will show up as the game develops and will be more spread out throughout the days, so keep an eye out for that! :)
