This is a very solid concept; It’s genuinely interesting/engaging and I want to play more, with a major “But,” point of gameplay feedback: the inability to move the towers feels really ,really brutal. I understand from the tooltip that it’s unlocked later, but I’m on screen three with thunder unlocked and I’ve already restarted twice after regretting tower placements, and having misunderstood how best to use thunder I feel I’ve made mistakes again and the upgrade is still nowhere in sight. With the cost scaling (which is fine, this aside), the difference between “good” placement and “bad” is easily enough to restart over in the absence of a “move” option to correct my mistakes, and I don’t want to restart again. (I understand it’s possible (especially given the prominent “reset” button) that this may be an intentional aspect of progression and failure and trial & error, to maybe convey an idea or feeling relative to what you laid out in your description; this critique is purely about “the game experience”/how it feels as a “game”, not about the work as a piece of art)
