Thank you for hosting such a wonderful game jam and for your warm, helpful feedback.
I plan to add explanations for gameplay mechanics and puzzles in the future. Regarding All Rune, I also recognize that it eliminated the need for other runes (since collecting just that one was sufficient), so instead of making it overpowered once collected, I adjusted its spawn rate.
To go along with that, I’ve added some unique playable characters. I believe this addition will allow for a wider variety of tactics and builds.
Once again, thank you for playing and for your feedback.
