I will post this in Steam forum as well, but it's important to me that the dev hears it.
You are making CW: IXE with preset counts of units available in each stage. This is how you did it in Particle Fleet, and I felt it was a mistake back then too. The Creeper World games let you make cannons or mortars, for example, in whatever number you choose. This is how strategy games do it, and that's a big part of having a feeling of ownership and satisfaction in completing a stage.
By contrast, this game style you've made with PF and IXE takes that fun and personal strategy completely out of the picture. It's like if the whole of Starcraft was the campaign missions where you start with units and have to keep them alive instead of building your own composition and tech. You're not making a strategy game, you're making a puzzle game.
All the considerations (Max supply, efficiency, size, lore, etc.) can easily be fit to serve this game. This is the only way I will love this game, and I want to love it, because I know how great the Creeper World games can be.
Please give us Strategy, not Puzzle Pieces.
Thank you for your consideration.
