I love the art style and the sound design/music a lot!
I feel like the writing spends a lot of time on Ryan repeatedly asking the same questions instead of trying to adapt his next attempt to be more efficient or trying to ask questions to cope better with the (probable) death of Mike.
The writing also does a big pet-peeve of mine where they take the noun of the last sentence and turn it into a question for the next dialogue, in a game jam where people play for 5 minutes, you can't waste those seconds on dialogue like that. (That and dialing takes a little too long)
But I like where this is going and would love to see a post-jam version when you release it!
