Hey, sorry for the late reply but this is a great review!
I agree with most of your points of criticism. The minigames have some things to improve for sure.
The lack of consistent artstyle, depth, buildup etc are a result of a small time frame for just one guy. There was a lot of polish, dialogue and other elements I wanted to add, but I had to settle for a small scope.
Still, I'm glad to hear you enjoyed the game!
