Felt a bit awkward in the boss stage and some images having lower resolutions was jarring but I like your art style and the intro was amazing

Some weapons felt redundant and the switching was tedious, there was no punishment for death or reward for defeating enemies. Weapons could've added to your movement when using them since the platforming was not that special and to give a reason to use them instead of others
The sprites where good though

They don't call him Tesla cool for
