This is a great shooter game!
I'd like to leave few things that you guys can consider:
The red demons are very hard to deal with. Maybe lessen their spawn count, or reduce their damage, their move speed, or their health? Once they swarm on you, even if you jump from the second floor to the ground floor trying to hit them, they'll just continue suicide attacking on you. By nerfing them, players get more time to deal with those purple demons which are actually fun to engage with. It's cool that you can try strafe shooting, dodge their attacks and the most fun is you can try to headshot them unlike those red demons who just keep swarming on you.
Kudos for making these demons smiling and at the same time scary as shit most especially when you look on your side and see those red demons eating you to death.
The jump air time is very cool as well.
Would love to see more games in the future from the team.
Btw, high score is 5k. :D
Cheers!
