First, thanks to uploader for sharing and to developers for attempting to create a game. My initial impression is that the art is nice, but the hitboxes are awful, the controls are broken, and the quick-time events are annoying. Additionally, the main menu buttons and sprites are misaligned at 1440p. There is no option to change the resolution.
UPD:
I finished the game and unlocked the gallery for the two available characters. I found Melody's playthrough more challenging for two main reasons:
1) The game director spawns a different, often unbalanced, number of enemies each attempt. If three distinct enemy types appear simultaneously, it's impossible to avoid being overwhelmed. For example, if snake, dog and tentacles man will shown up in a same time you won't be able to block all attacks because enemies have different speed, and you have fixed time to play attack animation, so after succesfully blocked snake you will 100% gain achievement "physical activities with dog and tentacle man" . This makes it difficult to complete a level if the progress bar has already started, as you're constantly being interrupted.
2) Mandy's stand-up animation is longer than the dog's stun time. Consequently, if the game director spawns two or more dogs at once, the round is lost. The dogs attack faster than Mandy can recover and counter, due to her lengthy animation. This prevents the player from blocking attacks, even with perfect reaction timing.
