Especially one with a unique setting, such as this. It instantly worked with my wired XBox One controller, which is rarely the case, so that was a huge plus. Controls are okay. Roll/dodge mechanic is unique, which is nice. The feedback on dealing and getting damage is a bit too subtle, making it hard to know the difference between hitting someone and getting hurt. Overall, if you're a retro/pixelart Metroidvania fan, this is a nobrainer. A little extra polish (not Polish, that was fine :) ) would have made this a 5/5. Would have happily paid more than $0 for this!
