Thank you for checking out my game and rating. I really enjoyed your game too!
I think that's a fair criticism, level 4 is a step up in difficulty from previous levels. I think it becomes much easier when you constantly use the slow motion, but even then it is a step up from level 3.
Initially, we were not sure how early or late we wanted to introduce the slow motion, so we made level 4 but were not sure where it would be placed. Later, we decided that introducing slow motion early would give the player a better chance in other levels, where slow motion was not required, but it would make the player much easier to control. Its hard to say what the right decision was, but I agree with your feedback, good catch.
In your experience, did you get used to using the slow motion mechanic (space) pretty soon during or after level 4? Or do you feel like the onboarding process for that can be improved? We went with a more hands off approach of just showing the button prompts, but I understand some may want a more thorough tutorial.
How far did you get?
Sorry for the long message, I appreciate your feedback.
