Hi, many thanks for playing and leaving feedback, glad to hear you enjoyed the art, audio and general concept, I appreciate you sticking with it all the way to the boss.
You make a good point about grinding. I'm currently re-writing the RNG to avoid traps and enemies being grouped together too much as that is a major concern with this build. Some magics do double damage against certain enemies but I think you're right I need to make it more obvious with visual feedback when that happens. On the boss lead-up, I had a plan to add different tile art when nearer the top of the tower, plus boss music, good to have confirmation that it's worth doing for future updates.
Best of luck in your gamedev :)
