After 40min I stopped because all the upgrades you see are only earth health and I don`t need them^^
fun game!
you should maybe slowly raise the health of the standart little enemy (with recolour?) or right from the get go.
I ignored the dmg upgrades because the "main" enemys are 1 shot so all for attack speed.
Love the visuals and the controls. I already wanted to make a game with similar controls^^
