I can see that not knowing WHERE the enemies are comming from is not ideal... BUT...
I think there are many things that I made to help you know they are comming:
- when wave starts:
- "Wave incoming" sound plays
- Number of current wave shows up
- Everytime "princcess" is hit:
- "Queen hit" sound plays
- Screen shakes
- Her health is displayed above her
- Bottom line is used as a timer for when enemies are comming
Next time I'll try to make it more clear of where are the enemies comming from. Point taken.
Thank you.
