Definitely orginal and retro in its design! The idea is cool and we liked the small HP bar during fights.
The reaper, however, was not as impactful as we thought as we could easily ignore it.
Have you considered a feedback for XP / Lv gain? It was a bit difficult to estimate what it meant.

Initially the reaper was meant to be a hard enemy. But changed it to just be a wandering enemy to escape. With more time I would have made it follow the player if detected.
The log should show things like level up and XP gained. If it's missing then that's just an oversight as it was all in place to show. If you mean like a sound or pop up, it was intended. Some things got dropped/missed as deadline approached.
I intend to continue developing and improving. I also made a colorized version. Thinking of merging the two as like a swing to switch between the themes.
