Gave the game a good try, it is pretty fun even for people that suck at this type of games like me, has a good variety of enemies each one with their own behavior that you can learn (and have to survive) and a pretty nice variety of weapons to keep things fun.
The game is REALLY challenging and that's good but I wished there was a way to make it easier if needed, like one extra life or shields that could stack, I was not able to reach the final boss during my playtrough and it's a shame because I am sure it was really cool
The skins are a really good bonus to add to the game but I wish a button remapping was available since the Shift key was a little bit bothersome but is still a very enjoyable experience that I can recommend specially at the discounted price.
Keep up the good work!
