What an amazing project! The blend of strategic mechanics you have put together with the unit movements, the wall movements and the card types and placements are fantastic. I would have done my head in trying to balance these strategic elements in a way that felt great to play and you have nailed it. The cards reminded of Slay the Spire in terms of using the abilities on the cards and then drawing them to impact your turn but then the unit's movement made me feel I was playing a type of chess at the same time.
The sound effects of the units moving was very satisfying and the visuals representing each card were very helpful in remembering what I had placed on which tiles. I will come back to play more of this!
