Awsome presentation, on par with the best SEUCK games I'd say. But sooo hard to play - not sure but I think enemies (in normal mode*) take 5 to 10 hits to be destroyed (hard to count without dying). For old-school players like me who expect one-hit-kills (maybe two or more for special enemies), this is hard to get used to. It makes the game less "shoot-em-up" and more "avoid-em-all" - making it even more a test of memory than of reaction.
*That said I discovered your easy mode - not easy at all I think, because of tight space in some areas, but now showing the fun and potential of the game. I paid (again) for the full version just to say thank you for the "easy" mode!
Just maybe advanced SEUCK would help bring more enemies onto the screen further reducing the need for multiple hits on enemies?
Whatever, great talent you displayed here!
