Okay, here's some feedback:
1. The theme
I really like the idea for the game. It is really unique and i will give you 5 stars on this.
2. The gameplay
The game is really really addicting, but unfortanetly way too hard. I kind of got the hang of it after a while but still: Make it easier! Then i would love to play it more often. If you will make it easier in the future, just reply to this comment again so i can play the improved version! :)
3. The graphics
The graphics are okay, but as a tip: You can make way better graphics by choosing a nicer color scheme. Sites like colors.co will help you with that. Also, on sites like google fonts you can download pretty fonts.
4. The sound
I like the moving sound, the others were also not bad. The music unfortanetly got a bit annoying over time, maybe either make really calm or really upbeat music.
I hope my feedback helped you a bit. If you have some time, it would be nice if you checked out our submission too. Thanks! :)
