I am having some problems with the game, such as the loading screen getting stuck and not letting me enter. It also happens to me that it gets stuck in several places.

Great gameplay overall just need loading patches because it can interfere with gameplay whilst in missions. I personally have come across this problem due to the fact that in the middle of missions the screen loader would get in the way of my gameplay and can't move which causes me to die and/or ruin my speed time. I also found a bug in which if you reset a level as you finish it the clear pop up will be stuck in your screen until you reload the game. Gold needs patching as well because if it's scarcity it's a but hard to do upgrades and such. Camera angles needs major work as well because the character tends to zoom or lock in different enemies. I suggest having an option in setting in which prioritizes enemy lock on either by strength, distance, or danger level. Sometimes game crashes as well after finishing missions in which it doesn't count it as a run and you have to redo it in order to get the trophy count. But great game regardless fair pull chances in gacha and great skill based level planning such as weapons, attributes, and skill types. Some people are complaining about pull chances as a f2p but it's really just luck. I'm a f2p since the beginning and still am, I have 6 ssr characters now and 3 sir weapons. As much as it gets harder without stronger units it's not entirely impossible and the gatcha really isn't unfair just depends on your luck.
