Thanks for pointing out the bug; in regards to both your points I have learned that next time I’ll need to plan for more testing time at the end. I never had a a chance to play through the game all together because I focused most of my time on making it feel and control right, so the waves are mostly made up completely. Thanks for your time and comment!

Thanks very much! I think the main issue with the game is the lack of balance - the waves are very much haphazardly layed out as I didn't have time to sit down and play the game through a few times, adjust, and repeat, to make it challenging but doable. Also the graphics are lacking as there was no artist but I tried to focus on everything feeling smooth and controlling smoothly (camera motion, shooting, collisions etc.).

Again, thanks for the kind words!
