This is a very cute and nice game to play. I love the low-poly aesthetics. The gameplay is intuitive, simple, and fun, exactly what you would expect from a jam game. Witty writing, cute and well-designed models, smooth gameplay, all done by 1 person. That's impressive.
To make this game better, maybe increase the complexity of the level. It feels quite basic and bare, and the game ends unexpectedly when you thought there would be more. It is probably also a good idea to integrate a story into the game.
Nice job, nice game, nice doggy! ;)
