I have played more of this game than I really should have, but the idea and the execution are really fun.
if I have something to say is that I missed the ability to remove missplaced tiles, but the aspect of learning through mixing and sometimes missplaying might get lost if removing is too easy, so maybe only a limited amount would be nice.
Also, it might just be me, but the hero feels a bit weak at the start, being able to lose to the first monster if you are unlucky doesn't feel very interactive and lead me to try and highroll a defense chest early on most of the times.
But even so, it was a VERY fun game to play and mess around with. If you plan on working in this, I'll have to keep an eye on here
