I've put roughly 35 hours into the game now, and here's a short list of thoughts I have. You've done an excellent job and should feel proud of yourself for creating such a polished an enjoyable game!
- The Archer, even at level 3, feels too inconsistent for me to build a strategy you can plan around. Over time, you'll see that the enemy units will build up in certain patterns based on the power of the units you have. The Archer will take two shots across the entire enemy army without any player consideration for the ones I can see will wipe out an entire lane if unaddressed. If we could choose which enemies the Archer can target just like we can do with Spells, that would help to increase its viability immensely and make me want to pick the unit more often. The same concept applies for the Sorcerer as well.
- The Snitches should be limited to only a certain amount per lane, or introduced later. I've had games that would end early because I was massively overwhelmed by lanes filled with Snitches that make me lose most of my hearts, receive only low-power units/shields on my Cauldron re-rolls, and then get defeated in the next round despite changing my existing units to different lanes in an attempt to counter due to being under-powered elsewhere.
- There are times where I have extra coins and I have to re-roll dozens of times in order to start the round. Over time, you begin to acquire more slots for Cauldron rolls as the rounds go on. I'd like the ability to buy slots with my extra money from the Cauldron. Going all-in on buying extra slots to find the perfect recipe of units early on the of risk being overwhelmed feels like a great way to increase the strategic depth of the game.
- Having load-outs or a guaranteed unit type as a reward you can work for after a certain number of wins would be fantastic.
- Having a Challenge mode would be great- Limited Life runs, Runs only using certain units, Brain-Teaser runs that test knowledge of game mechanics, and Armored-Enemy Runs would be fun ways to add to the replay-ability.
Again, amazing job with the game- I love it and look forward to more!
