Hi :) I just played it again and it is still way too easy imo. I had my build fully done by about day 10 and I never had any problem to win a fight. I played again util day 15 and even though it felt like the fights were a bit tougher it still was not enough to make me loose a fight.
I think boss levels would be a nice idea. They should be a lot more challenging. In general I think the pacing for the difficulty in general should be faster. If the player can “finish” a full build in about 10 days then this should be the final level of the run and it should get more difficult quickly. Maybe day 10 is a boss level and after beating it the player unlocks a new class/faction for the next run.
With this you can make sure that new players understand the concept and do not get overwhelmed by too many different units. also experienced players will have access to more units and cool combos.
IMO playing after the build is finished feels boring. The fun part is assembling the team and trying to find the pieces you are missing in the listings. Once you have that there is nothing to do really. So I would make it so that it ends after this.
Also I now played with a mouse and the scroll speed in the listings panel was way too slow.
Here is my build:
