I just finished the game, and although it didn't have native gamepad controls as I was told (except for walking and looking), I used 3rd party remapping software to use my gamepad and very much enjoyed the experience. In fact, I went back and replayed it a few times to get the achievement where you take no damage, which wasn't easy but satisfying once I unlocked it.
It reminded me of the old-style Resident Evil and Silent Hill games in some aspects, while in others I could see the "Indie" in it. What I mean by "Indie" is that most Indie developers put more love into a game than a studio would, and it really shows with the uniqueness of gameplay mechanics. I was very intrigued by the "Pockets Balancing" mechanic; I'm assuming it's because Liam craves perfection. Also, the combat, puzzles, story, and audio were great as well. The jumpscare where I went back to fill up the bottle in the bathtub really got me good too.
I think you did a great job as a solo developer. I myself am a solo developer, and I know how much work is involved in game development.
As far as what I would like to see added, if I had a choice, I would say that you really should add full native gamepad controls. I, like most gamers, play on a TV screen with a gamepad as opposed to a monitor with a mouse and keyboard. It's not a big deal, just something gamers would enjoy.
I would also love to see a sort of "Nightmare Mode" where one hit kills and more enemies spawn.
Either way, great job, buddy, and I look forward to future updates and content from you; you have talent.
