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.
