It has good mechanics and fun upgrades but the gameplay is not super engaging and it needs more completion and replay mindfulness

Very crude but fun puzzle game which similar to Gnorp Apologue. You should know the game tag is wrong. Tower defense puzzle with some incremental taste. Not an idler.

Played a lot of idlers and a tower defense idler seem fun, but this is just boring (which I know sounds crazy for a idler). The prestige loop is unsatisfying and the tower defense is very basic.

This is a puzzle game designed as a tower defense game. The difficulty in combining different prestige skills and the satisfaction of the broken prestige skill in the end game made this game good albeit short.

The idea is kind of there, but it is simply not fun

This game is more of an incremental game than an idler. There is also alot of strategy involved. The game prioritizes trying different builds and prestiging again. It is not a game that is mindless like other idlers. It really scratched my problem solving itch.
