Great job on this, everyone. First of all, the lore. I really liked the story where you are going back and forth between time period in this knight's (king's?) life. You did well using the way the characters controlled to express their differences in age.
I also liked how each time you got an upgrade, the character demonstrated in what situations you would use it. It made it super clear what each upgrade was for and even may have made you recall what area to go back to.
However, it was very tough to control. The jumping felt unnatural and all of the actions felt very slow. Maybe this was intentional in a classic Castlevania type of way, but it made exploring and backtracking tedious.
It was also easy to get lost. A lot of the interior areas looked similar, so it was difficult to get a mental map of the world until I had gone through it several times.
Overall, I think the team did a great job. It has a solid story, great art, and the final boss was really cool.
