The base game is incredibly poslished and eye candy. Esp compared to my programmer art.
Only thing missing is perhaps some more interesting enemy types. maybe there are some that were there but i didnt notice, or just have some cool boss rounds. (or both)
I'm working on an arena rougelike as well, and I have trains that run you over. Which, ironically is the most adrenaline rushing part of my game. You can only dodge (not damage) them, as compared to the normal enemies which you can ofc obliterate to your heart's content.
