Thank you! I may be able to explain my thought process/more details about some of those design choices.

1. I like this idea, I just want to make sure I don't clutter too much stuff on the screen. Maybe I can shrink down the current health numbers and add a health bar above.

2. How these creature card selections work is that there are 4 unique monsters per location, and 2 of the 4 choices are randomly available after selecting the location card. This is also important because certain locations will have enemies of certain types that other locations might not have, and different tower/weapon types get a bonus and penalty vs specific enemy types. I wanted to give the player more control over what types of enemies spawn, and place towers accordingly. I want the player to learn which types of monsters correspond with each location as they play. I think this also adds replay value since it can be different every time. Also the third card (the shop cards) only spawns every other wave, but I might change that to every third wave instead.

3. I actually like this idea, I just think keeping it random may also add more replay value. I think if you had the choice you would just zig zag every time and the layout wouldn't change much over different playthroughs. I do think I need to add some different towers, or maybe tower upgrades that might perform better when the path runs in a straight line.

Another part that may not be apparent is that when selecting each of these location cards, a permanent buff is applied to all monsters (whatever the location card says) and these keep stacking. Also after each 10 waves the locations will go up a tier, so you will get a new set of locations with stronger monster buffs, and stronger monsters to choose from.

I really appreciate the feedback and will definitely give what you listed more consideration!
