Thank you so much for your feedback
I already have a new build ready that fixes some of these points - like more variety in music and removal of the time limit and strike system.
There is also a restart level button and much more. But since it is still in rating period, I cannot upload that.
I like your suggestions regarding gameplay mechanics and really wanted to implement more of them together with more interesting levels, I just ran out of time sadly. I often start to polish when it would have been better to add more to the game first.
Will definitely keep working a bit on this one, so it feels more complete.
