I like the story setup and vibe! The music and sound effects are great. I loved the robot who wonders if "hammers aren't very good for fixing things", that made me laugh. The way the hammer charge is actually used to go back and solve previous puzzles (instead of just passing obstacles) is great.
Some areas for improvement:
- Text speed is way too slow and unskippable.
- Character movement feels too slow.
- When you turn around, your character seems to change position slightly (and so does your collision box).
- Control mapping is strange. I wanted to use the hammer with my right hand (moving with left) so I ended up with my hands overlapping.
- It's strange how after the hammer charge fills all the way up, you actually have to hold it a bit longer to make it work. It should work as soon as the bar is full.
- Using the rising platforms for a boost only seems to work if you jump right at the start of their rise, so you just have to guess when it will go, which doesn't feel satisfying. I would study the moving platforms in Celeste for an example of this feeling nice and consistent. https://twitter.com/MattThorson/status/1238338581971603457
- If you touch the spikes, it's very easy to lose all your health before you can do anything.
- The game went to a black screen multiple times for me, so unfortunately I couldn't finish it.
Hope that doesn't feel too negative. Nice job!
