I notice the binding of isaac inspiration and I love binding of isaac, but I think you should work more on that idea.
The rewinding mechanic is really fun to play with and you can easily exploit enemies to return to their original location so that they never get to you, it is really fun! I enjoyed the game, but try to add it content in a future update just like binding of isaac!
Now what do you think of playing my game?Actually the mechanic is very similar to yours. give it a try and a rating maybe!
