You've come a long way, this game is pretty tight, I had a blast playing through all of it.
Dope enemy designs and varied attack patterns, Deadly Mode truly is challenging, the Hive Mind Trooper is the toughest of them all, as if they knew the Snowflake was truly OP.
The minibosses and boss fights are very challenging and well made as well. Volodiros is my favorite one, even though he seems like the easiest one. I thought his last phase is too short since you kill him so much faster than the other bosses. He doesn't seem to change much from Normal to Deadly except for the bigger HP pool (probably because it's the boss you can hit the most inbetween phases).
Mizerantha has the coolest attacks, touhou-esque kinda fight, distinct phases with a lot of charm. Karkambian probably the hardest one, i-frames - the Boss, very tough fight in Deadly Mode.
I have one question, what's the blue Z indicator below your health for? I tried pressing some random keys and it didn't seem to do anything.
Overall very fun to play, good work Taska.
