First of all, thank you so much for taking the time to provide us with your feedback!
Regarding the UI, we’re definitely planning to improve it even more, adding additional tutorials, effects, and features to help players better understand what's going on during the game.
As the level designer, I totally get the issue of resources not being closely linked together. Honestly, I’d love to have more resources at my disposal to design even deeper and more engaging levels. In the current version, I’ve done my best to balance the resources, so players have a fair chance to progress through all the levels without feeling overwhelmed by too many decisions. That’s why it might seem like there’s not too much thinking involved to get through each level.
I’ve taken note of the points you’ve mentioned regarding level design, and we’re definitely going to work on making things more exciting in future updates! Thanks again for checking out the game!
