In this game you play as the titular Dashula, the fact he can survive so close to the sun implies he is in fact the strongest vampire alive and actually has increased fire resistance, only truly perishing when the sun makes direct contact with him.
This truly implies deep lore as to the origin of Dashula and the sun, and the dualistic philosophy of life and death. I'm not sure what the wooden stakes represent, probably capitalism or something.
Also the jumping and dashing feels nice, and even though it can be kinda hard the game is short enough that it never felt too frustrating. Level design is done in such a way there's often multiple paths which does encourage replayability.
