Neat to see another Metroidvania here! Haven't seen that many other people with this take on the theme. Though, I think it needs a HUD, and the difficulty felt pretty overtuned. Sometimes it felt difficult to figure out if I have the upgrades needed to progress or not. Ultimately I didn't finish the game just because after you run out of enough lives, your run is basically toast since you just don't have enough time. This is pretty demoralizing, and then you just have to do the same things again to get back to where you were before in the next 10 lives. I think the premise is good though, sorry if I may have criticized too much. :)
