Really fun resource management game! The sound design was super satisfying and made it fun to just organize my cards around the screen while waiting for the processes to finish. Loved the art direction and illustrations! This game definitely made me wanting more! I also really liked the stacking mechanic which made it easier to manage things, and getting a big 'payout' of gems from a big stack was really fun.
I tried my best to break the game as much as possible, and I did manage to create one bug at the very end of my playthrough by making a huge stack of gems. Once the stack reached a high amount, the card stack moved off screen and was irretrievable. (at 9:55 in my video).
Other than that, the game played super smooth and I really loved the tutorial system. Again, excellent sound design. Really nice sound effect that catches your attention. It was also an amazing way to teach the player one step at a time without overwhelming them. I also love how the recipes get added and always have it as reference.
Where could you see this game going from here? Would the player be brewing specific recipes that are being ordered by a witch? Are you combining materials to spawn minions in a defense game? Could it be a way of 'brewing' your own deck in a deckbuilder PvE game? I'm curious how you could add interesting decisions beyond simply climbing the 'recipe tree' for the sake of reaching the top.
Really well done and I look forward to seeing how this can branch out from the solid core you've developed already. Great work!!
