I like how the game feels - you clearly made effort so that hits feel impactful (perhaps even slightly too much - my screen was shaking violently!). The little square guys look appealing, items (and especially the shop UI for some reason) look really good, sounds are quite cool
But by the time you get to 3rd level, it gets *really* repetitive. I got to lvl 5 400 gold and it was kinda tedious - same enemies, same enemy placement. It got even more boring after I bought the staff and couldn't change it back, it was just left click spamming.
So, the premise is good, execution is really great, but definitely needs more variety. When playing I thought that some movement - dash ability perhaps - would really fit with this.
Also sword >>>> staff
