It took time to understand, really difficult to grasp without tutorial. But, once I have a good handle on things, that was a really fun experience, quite addicting too. Really cool art style choice too, really nice job!

I really enjoyed your game! Usually people said that to me about my game, but here I understood why they said that, that the game opened up to them in a new way when they learned new mechanics.

At first I was just picking my offense and defense. After a while, I noticed that the things I choose (in which there is no word) turn out to be abilities in the upper left corner. And I have to choose attack or defense to activate them.

Initially I was just looking and didn't understand why the character was doing some extra action.

Oh, correction. Read it in the comments. Turns out fullscreen takes away the text display. However, for your game, you could call it a plus. I was able to navigate without text :D

So, I interrupted. Perhaps when doing an attack/defense, it would be worth doing some sort of glittering line fly through from left to right in the background of the skill. And if the skill is completely full, you could make that line bigger for the player to notice. You don't have to make the interface stay within its zone. These lines can cover the center of the screen a bit so that the player pays attention to it. However, this is just an example.

The gameplay is very addictive. With very little health, I made it through a few more floors on the shields only. Got to some floors with no background wall, just columns. Again, was without text, don't know which one is which :0

In general, you can seriously try to practice readability of the game with the erasure of the entire text from the game :D

The game is very interesting, addictive strongly.

Really cool game! Nice concept and nice art! Really fun to play, good job!

Suuper fun and addicting game !! I found myself playing this one for a while and a well polished game too :)) Good stuff overall :D

Made it to level 14, going with as much offense as possible lol. It took a bit to figure out, but once I did everything worked really well. You did a good job of making most of the decisions not just "choose the higher number"; like exploring is a trade-off between moving far and landing on a beneficial space, and combat is a balance of using naturally high rolls vs. activating skills.

I like the concept here - the combat system and movement felt unique and fun to use. My only gripe is that the game was pretty zoomed out and low-res, which made things hard to see. Other than that I really enjoyed playing and loved the concept. Good job!

Nice solid game! The overall atmosphere of the game was on point, and I played a couple of runs just to see how far I could get- very enjoyable once I figured out how everything worked. My final run ended at level 12 or 13 after I took either 12+9 damage or 129 damage on a crit.
Since you asked for critique- the biggest space I can see for an improvement (besides a possible tutorial and extra features now that it's not on a time crunch haha) is in the UI. One I got into the rhythm of it, I could tell when at least some of the monsters would attack, but being able to see a turn order would've been very nice, as well as hopefully being able to see all my unlocked skills at once even if not all of them are active at a time.
On that note- skills! I liked having to use attack / defense to charge skills, but the ui for them was also confusing and probably needed adjustment to make it a bit clearer, especially since it was bugged for fullscreen.

This is really, really good, actually. I think it's a fantastic idea that you should continue fleshing out. 
Unfortunately because I'm an old man who has resolved to be honest, I have to take off a few points because I went and checked out your previous game that this is 'based on', and it's kind of clear this is just a continuation of that game, to me. Maybe even the same Unity project (with lots of further work, of course), since the files are even both named "towerknight".  Don't get me wrong, it's obvious that you've put a ton more work into it. This isn't a knock on the game. Just on the submission for a jam, I guess.

Since this jam is supposed to be a new idea, a fresh start, I had to take off a few points from my vote for that. But seriously, I think this is great. Fleshed out, I could see myself putting a lot of casual hours into a game very much like this. Great work :)

You have a great art style, but without a tutorial it's really hard for me to understand how to play. But it is very cool game.

Definitely needs tooltips for all the stuff going on, but it's cool
