Nice novelknight model and fun gameplay!
I like the different types of upgrades you can get as well as the different and unique environments in the game.
Once I got the AOE sonar ability, I just spam it for winning without taking a single hit. I don't think I ever used the dodge.
I also like that you can do NG+ after beating the boss, so you can keep your upgrades.
Some improvement suggestions:
-Add an interaction with Shiori! She's just standing there and I was expecting her to say something to the Novelknight before we begin the quest.
-White text on light backgrounds was a bit hard to read. Try adding a dark background or outline to them.
-Enemies should spawn invisible and only turn visible after they've been moved to their positions. It was funny seeing them spawn in the middle of the room and then fly to their spot. XD
-Music and sound effects!
- Bug: Current HP didn't update after getting the max hp upgrade, so it looked like I had less HP than before. It got fixed as soon as I got hit.
It would be nice to see this game get some additional content, maybe a storyline, some more polish on the presentation and UI, and of course have some audio to complete the experience.
