The gameplay is relatively simple but very fun, the levels are truly rogue-like in their randonimity, the unlocks provide a good amount of purpose but even after everything is unlocked it is still fun!

Even better -- it's in active development! New content is continually being added! It was a steal when I got it in a Humble Bundle months ago.

I'd easily pay the regular price of $15. When it's on a Steam sale -- go, go, go! You'll get your moneys worth (IMO).

I look forward to how the game evolves and look forward to more from these devs. They are the best sort

UPDATE: I had originally reviewed this during early access and holy cow they have added so much content! I had looked forward to how it evolves and it has done me proud. Easily worth the price even without all the recent additions.
