Definitely, I’d love to. Here are my 2 cents:
- Instead of/or in addition to increasing the speed over time, you could try to add different type of enemies or enemy waves. I did a Slow Run of almost 2 minutes and I got a bit dizzy, maybe increasing the speed slowly or adding difficulty in a different way would work great.
- It would be great to have different type of coins, with different values, bigger values more difficult to catch.
- Adding more features to the rockets in the store would be really nice as well, such as faster boost or improved stabilization system.
- Something I’m a bit confused is how the “Level progress” bar works, it would be nice to explain it somehow.
I hope it helps for future iterations. Again, Great job!
