Thanks for trying it out, mate!
I'm currently working on adding a checkpoint system so you can start from the last level you beat. It's already functional, but I'm still tweaking the design a bit to make it feel smooth and user-friendly — especially on Android.
To encourage players to aim for higher scores, I'm also planning to add a CG gallery with unlockables based on score milestones. This CG gallery will come later, once I have more content — maybe next week.
