Thanks a lot for the feedback! I thought about lore this week and I kid you not, I thought about some wizard too! But he actually punished a gambler who had lost something that belong to the wizard. But I might talk to more people who have better writing/narrative skills on that front.
I plan on adding some more content to the game in the future, like guns and power ups and bosses (common stuff for shooters, can't stray too much from my origins).
