Interesting tower-defence like game. I like the "guard your treasure from heroes" premise.
I felt kind of overwhelmed by the character and trap stats and to be honest I am not sure if I understand them even after few playthroughs. The fact that my minions (towers) have health is interesting, but it made them feel "weak". Especially when my archer was dying fighting a hero that doesn't really looked like ranged unit.
Overall the game felt difficult to me. I would like to start with some easier vawes to give a player space to learn what your units does.
Honestly - I think the biggest downer for me is the CRT filter on the top - in combination with small font it hurt my eyes to read, which is bummer in a game where the text is important. Making it optional in settings would be a great improvement.
Pixelart assets themself are really nice.
Tiny thing: Music slider in options has weird range from "nothing" up to half of the slider to "argh, my ears!" on very right. It also seems to be not saved between scenes.
Regardless all of my critique, the game core works and I see a lot of potential in it. Good job!
