Seemed kind of strange that burning houses are shooting fireballs. Being able to refill water was also a strange decision. I felt like needing to constantly reload for no reason was just a chore, so it could have either been scrapped, or been fleshed out into a mechanic that added something more to the game, e.g. needing to collect or ration water, or finding refilling stations.

As someone else mentioned the hitboxes were way too large, making it hard to judge if something was going to hit. Dodging fireballs and getting the right angle on houses was mostly just a chore, instead of being a fun challenge.

The music was also a bit repetitive.

The hitboxes are a bit tight, but loving bullet hells I enjoyed the game very much :D 

Like the in game tutorial part. And the way the character aiming and reloading.
Yet a bit hard to me to dodge all the fireballs )
Good job!
