1. I thought the puzzle was nice and also just the type of puzzle that I would want for a game like this.
2. More text/texture-based puzzles and riddles would be nice. I also feel like the zero-gravity movement is fun so maybe a small maze or obstacle course could be cool
3. I depleted the O2 meter the first time I played. I think that it would be really cool if this game had a really small O2 meter at first and as you played and failed you grew your tank for the next playthrough.
4. The animation was pretty dang cool. Maybe adding an "overheating" mechanic would be nice (where if you use it for too many seconds consecutively it clogs up or something; this would force the user to use it in short bursts and not just spam it).
5. I'm hoping for the next playtest to have some more puzzles and also just some sections to navigate between puzzles. Again, I think the movement feels really interesting so maybe longer, debris-filled hallways would be nice.
6. I just think the game is charming. I really hope you stick with the "endings as achievements" style where you are encouraged to try everything. I think a lot of personalities can be infused into those ending flavor texts.
7. I think the battery mechanic doesn't add to the game at all. I would just have it where when a puzzle is solved, the path to the next opens.
8. To summarize the things I'd like to see:
- More text and texture-based puzzles
- Zero-gravity navigation challenges (mazes, obstacles, things between puzzles)
- Lots of ways to fail (multiple per puzzle, burning, no O2) with flavor text for each
- Tightening up the door mechanics
Overall, really cool stuff y'all. Excited to see what you have for the next playtest.
