An interesting game, but a bit too short for the emotional story to make any impact.
The standout aspect for me with this game was the combat: while pong gameplay was never my jam, I did appreciate the cleverness in designing such a gameplay system that was not only fun and challenging to get good at using, but subtly reinforces the story as well by showcasing the cooperative relationship between the boy/man and their dog. Bosses were fun and interesting to fight in an Undertale-esque way, and the final boss was brutal and standout as a setpiece.
Outside of the combat, however, the story felt very overly sappy and hackneyed, and wasn't presented very well: rather than making me emotional, it more made me laugh at how much it was trying to speedrun through the whole thing, which made it feel all the more flat. I felt way more attached to my dog through combat than any of the cookie-cutter dialogue and cutscenes.
Definitely a good attempt that could be great if it just had more meat on its bones, more time to get the emotional connection it is going for.
