This is a very nice game, it really hits my sweet spot for athmospheric games with a lot of tension.
The reload mechanic is how it needs to be, makes me wonder if it would work well with a revolver too.
I only have two things to add: the ennemies floating above ground are a bit too hard to see coming, maybe the levels need more small plants, and the audio could be more useful, it would be nice to hear ennemies coming.
I would love to see this expanded on!
