✦ AI summary

Project Rhombus is a simple rhythm game centered on timing arrow blocks to the music, featuring appealing tracks by Hinkik that players generally enjoy. Players are divided on execution, with some finding the straightforward concept and progressive difficulty scaling satisfying, while others criticize inconsistent input syncing with the music and claim the difficulty spikes feel unfair or overly punishing. The game appears best suited for players seeking a challenging reflex-based experience rather than a traditional rhythm game.

That is basically the entire concept, but the timing gets much more demanding as I move through the difficulty levels. I like games that can explain themselves in a few seconds, and Project Rhombus definitely does that. The controls are easy to pick up because I am mainly using the arrow keys to move the rhombus into the correct position. The challenge comes from having to react quickly while also keeping track of the rhythm. The normal difficulty is manageable once I get used to the timing, but the harder modes push my reactions much more. There are four difficulty levels, including Easy, Normal, Hard and Expert, so I have a clear reason to keep practising once the basic controls stop being a challenge. The music is probably the strongest part of the experience for me. The electronic soundtrack gives the game the fast pace it needs, and the arrows coming towards me fit naturally with the beat. I also like the very minima…

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
