Glad you enjoyed it, there do tend to be lulls and peaks in the action and whilst we would have loved to add upgrades and new mechanics we ran out of time. ( we wanted a summoner enemy and so on) You'll be happy to hear though there is a "Forge" that does what you mentioned and more ;) I suspect we needed to toggle the rarities a little bit to have them be more common. Thanks for playing though! Appreciate the feedback
