I like the graphics and stuff. Concept's pretty interesting. and so is the plot.
The problem is the game doesn't feel very fair overall. The player moves too slowly and has too large of a hitbox to easily dodge enemy bullets, and the bullets also feel like they do too much damage to the player. The duck mechanic also isn't helpful because you can't duck in the boss section. It feels like you just take damage for no reason sometimes.
I also don't like having to restart the entire game every time I lose all my lives. I understand the checkpoint system was glitchy, but not having it still made the game not very fun. Also, for some reason in the boss section I couldn't turn around?
Overall, still a good game, it just needs a lot more polish.
