Thanks for this great comment! I'm glad you like the art, it was meant to be just for the prototype but I kinda liked it and didn't know what else to change it to so I just left it. Also, I was meant to point out in the game that the enemies are dumb and try to move to the square closest to you, even if there is a wall in the way, but you seemed to figure it out anyway. Yeah I also noticed that the enemies would 'merge' into one and spent a whole day trying to fix it but I just couldn't with the way I did it, so someone gave me the idea of making it a 'feature'. I still would've liked this to be fixed but it doesn't seem as bad because I pointed it out in one of the levels. That is an interesting idea of being able to rewind the player, but I feel like that changes the game a lot and isn't really necessary. It could be good but I personally like figuring it out and being able to do the whole level in one go. I mainly think this because it doesn't take long to get back to where you were, but still thanks for the suggestion!
By the way, I've seen some comments you've left on other people's games as well as mine and I really have to say thank you. It's so nice that you put so much time into commenting and properly reviewing and even finishing peoples games :)
