I want to say that I am a huge fan of the outcome, but honestly things that are frustrating to come by are:
1. There is no option for full screen, or at least I couldn't find one, which later will also go down from not being able to see everything (I've used the magic of zooming in the page)
2. Screen shaking which really downgrades readability paired with that font
3. After you level up you don't have a grace period when you can see options, you can just click anything, which is REALLY annoying especially when you are in a shooting spree
4. The lag when enemies clump up together after not being able to handle with most of them
Overall I would say the games is pretty fun and makes me wanna play it even more, but for me things that I noticed are 'game breaking'
Would rate 8/10 if not these 'bugs'
with them solid 7/10
