This game is enjoyable, even if it isn't the greatest game ever made.
The concept is nice, and one that is seen surprisingly rarely, even if it seems quite obvious.
The movement felt a little slow, but this might just be my own preference. It wasn't unbearable, but it just didn't feel right, perhaps with a bit more animation and some changed particles it might've felt better, but as it stands Id say its just serviceable.
The presentation is overall quite simple, but it does the job, apart from the aforementioned walking, all the art and animations are quite nice. As for the music and sound effects, it definitely achieves what it's going for, however the harsh saws and squares were a little unpleasant to the ear, especially at the start. Also, the sword is pointed the exact opposite direction you are aiming, this felt really weird, but I got used to it pretty quickly, just something I thought I'd note.
Challenge gameplay felt overall pretty good, the lack of variety was a bit disappointing, however I understand that concessions have to be made in a game jam. The difficulty was a bit on the low side, but I did manage to fail at one or two collection challenges, and I didn't perfect a few of them either. One thing that annoyed me quite a bit was that the UI often blocked the enemies/shards, which made me lose perfect a few times, a simple fix would be to make the UI smaller, or to simply zoom the camera out a little bit so you can compensate for the blind spot in the top corners.
Board gameplay is good enough, although the communication could do with a little work, telling the player their min/max rolls would be a good QOL feature, and so would some indicators telling you which "portals" go where. It was also a bit frustrating, that you couldn't look at a map while at a crossroads - the place where you need to look ahead the most. Apart from the communication issues, the map was built pretty well, and some of the "grinding loops" were a nice addition, although because of the lack of proper marking, you don't really know when you're even going into one. I also enjoyed the portal just before the end, as it was a nice QOL feature which prevented me from having to do the whole board again, although I can imagine that even with that feature, if one were to have a <100% chance to roll a single number, it could still be quite frustrating.
As for general communication, the tutorial at the start is probably good enough, although it felt very strange, how it explained 2 tile types, but not really any others, whereas the types it explained seemed to be the most self-explanatory, perhaps either describing all the tiles or describing none of them could've been a better option.
I overall enjoyed my time, and it was fun slaying 10 knights at once, however it did seem to be bogged down by repetition a little bit - at one point I got the exact same challenge twice in a row, that was weird. Good luck and thanks for making this!
