For your first game, I'm very impressed! The art style for this is great. I do love the concept of the minigame, however I didn't realize I could purchase upgrades, so I missed out on some things.
The game is well story-driven in my opinion, gameplay was nice and well paced. I had not issues with this at all.
Overall, I did enjoy playing this and would love to see more of your work in the so distant future!
