Like most other transdimensional games its going to have its frustrating and confusing moments, but this is an amazing puzzle game and one of the best mini golf games ive played hands down. Its surprisingly accessible but intimidating to look at (especially later levels [understandably]). game is also optimized to hell and back and runs fantastic even on later levels.
The final level is something i dare not to spoil, its thats good of a twist.
An absolute staple if you like mini golf and/or transdimensional games

4D Golf is a perfect game for reasons I cannot describe without spoiling much of what makes it so special. If it even remotely interests you, please go play it and play it all the way through.

I will say it is not a particularly hard game, nor is it particularly long. Half the time it was just my (lack of) mini golf skills that really got me in trouble - and the game doesn't really care how many strokes you take. Just beating these levels is the real accomplishment, and you can return for par or better scores later.

Mind bending, takes a while to really understand how the 4th dimension works but you really do get a solid grasp by the end. You would rarely get anything close to par on your first play through, but when you go back and try again you realise how much you've learnt. The final world I genuinely didn't understand and would finish those levels by total trial and error. A mix of puzzle game and mini golf. Let down a little bit by underdeveloped UI and 'game' aspects being a little lackluster, no real scoreboards or much for keeping track of your progres, lacks a good drive to go through and try everything again bar a couple of simple achievements which I think is a missed opportunity.
