I respect how hard it is to make a good game, but this is just downright terrible as it is now. Every aspect of the game just blends together, and is virtually impossible to distinguish between runs and even individual rooms. not to mention the ripped assets from a game "inspired" by tBoI, the downright jarring screen effect every single time you shoot, no items, (seemingly) no different rooms except the boss, the physical inability to progress past the first floor... i would be more lenient with my judgement if it were at least free to play, but charging people to play what's *barely* a proof of concept is just scummy.
That said, I like some of the deviations from regular Isaac, which I hope to see more of, such as being chased by troll bombs and needing to shoot them to blow them up away from you. maybe with some more content, there could be a reason to bring them into another room and use them to save a bomb.
