Hi! Thanks for your interest :D
The game is still in pure development. There will definitely be lots improvements and more content.
This version is just an alpha version that seeks to get feedback on the gameplay in general, in particular the difficulty.
I try to make the game difficult, but not frustrating, rather a rewarding difficulty.
There is no way to achieve that without other people trying it and giving their opinion/feedback, bad or good.
So tl,dr the final version will be very different.
