First of all, thank you for the feedback! We really appreciate it :D
We are fully aware that the game is not balanced enough and that the rolling mechanic can be exploited. Negative damage actually heals enemies, which is completely intentional btw
Thanks for the review! There is much more to update other than just sound. We will keep on polishing and expanding the game further this year. You may star our GitHub repo to see the progress. https://github.com/MiraZzle/ad-caelum
