You mean a 2-3 hour run? I don't know if I would make them last that long. The doubt that I have is bound to the core action of the gameplay which is hover above the enemies. If I think of other roguelikes, like The Binding of Isaac for example, the gameplay keeps the tension high with the enemies that you have to physically avoid. It might be interesting, given the gameplay that you implemented, to add enemies that you have to avoid, enemies that you have to kill in a specific order etc. I think that just hovering could be too repetitive the longer you play. Just my 2 cents of course, but I like the game and I'd try it again when more content is added, keep up the good work! <3
