This game has a lot of potential, but it needs some improvement with the UI and other tidbits to truly make it shine.
The catching system: i like it, but if you add an option or additional key press to use a pokeball to catch a low health pokemon that would make it less rng based. just for when this game really takes off.
Map: one of the upper corners could house this, just so it's easier to navigate the world
Evolution: at least try to get this implemented to where you can evolve your party rather than have to find a replacement for it because it can't keep up
Bottom of screen: with some cleaning you might be able to resize it so it takes up less room and still has legible text so we know what we are doing.
i don't expect any of these to appear overnight, and in fact i won't expect them in any near future update. but if you do update this game (and i sincerely hope that you do) that you try to add these to it, and expand on the story as well.
2.5/5 the potential is there, but needs some more meat on its bones to truly shine
