I know that it's an overwhelming task to make a game in UE for the first time. It seems to be easy follow tutorials but once you make any custom mechanics it can become nightmare. I like an art style, as I understand you make it in Blender and this is really nice, cos' it has authentic style. To the cons. You need to take a closer look at UE input system. If you are using UE5 there is a new input system which can help you to choose how to use keyboard keys. For now in many cases I need to press keys twice to make a move (it's probably DoOnce operator isn't reseting). Second thing which is probably most problematic for a lot of games here. Player positioning in a world and camera settings. the problem is to design a world suited for grid movement. if you take a look at Grimrock 2 camera take a part of the floor so it could be something on a floor which can be found and everything is actually made of blocks even if it's exterior level. It helps to build a world where there is no objects which block player movement or overlap with a player. I need to tell one more time that I really like art style and appreciate you put an effort to make it look great. One more thing you need to make a shipping package for final release, you have debug raycasting on, it will stop it. )
