I bought it on steam and thuroughly enjoyed it. The art is nice, the gameplay is solid and easy to learn, and pretty replayable due to its short length. The only real critiques I have are difficulty, since I played through the game three times and didn't die even once, and extra content.
(Spoilers ahead)
If the game were to get big updates at all, I'd ask for a harder difficulty option for those who want a challenge, and perhaps some more content with hoodie and Mari. To be honest, I only played the game a third time because I saw the comments and thought to check if there was another ending for having mari and hoodie eat the same amount of donuts, which there isn't. Mari takes priority when the eat the same amount. But I really like the idea of some more romance options between Mari and hoodie. Maybe an extra collectible in each stage could be a gift or bigger donut that you give to Mari whenever you come back to meet her, which would make her love you even more and result in a new ending where Mari and hoodie grow together. Also, I'd like to have more dialogue during the endings, specifically mari's ending. Dunno if any of this would even be possible or ruin the feel of the game, but I'm just making suggestions.
