Smooth and polished mechanics. Some feedback:
- Good implementation of the theme.
- The background music doesn't loop so if you play long enough it just becomes silent.
- Surviving felt very easy and was not a challenge. Changing the level design or the enemies could alleviate that.
- Although the input timer mechanic is good in theory, I didn't feel like it impacted my gameplay at all. It was quick enough to the point where I forgot it existed. When I did remember it, it just detracted from the experience.
