I really wanted to finish this but I ended up rage quitting haha, the save spots are really brutal and I powered through but then after progressing a lot between saves, I swapped worlds to fall into an inescapable pit. Brutal! I guess if that's what you were going for you succeeded haha but losing that much progress ruins the fun and an open world metroidvania doesn't need any more backtracking from losing progress.
As a game overall, I really like it though. The graphics work well, the level design is good and the inverted health mechanic is genius. I may be back to finish it when I've calmed down haha
