Great visuals and sound, but i find the explosion of the enemies to not match the rest of sounds too well. This could be due to personal preference but if anyone reads this i'd like to see if they agree or not. To me what doesn't match is that kind of distorted echo that it does, while the shooting effect has a clear, smooth sound and is a very good one.
The controls and overall game feel are super smooth.
Great job, It's a fun game! Cheers :D
