I might just had a ton of bad luck, since out of 10-ish dice rolls, I got two upgrades haha. I would have liked if there were a way of having some sort of manual control about the upgrades I get. And maybe to incorporate the theme more, if the procedural levels were chosen (in lenght) by two dices maybe, or the number of enemies it would be cooler in that aspect.
But other than that amazing game, while I was playing it I thought the team was way more than 2. Lovely art, lovely code!
