This is a very addictive game but there are major drawbacks that made me quit: your weapons REALLY suck, the enemies' are way too deadly, the power-up system is all random and lacking in all sorts of ways and the random generation isn't much fun when it means you will too easily die after a few waves, no matter how trained and prepared you are. Also, while it cruelly lacks variety, I've rarely encountered any boss in my nearly 12 hours of play. When I did, I was on a one-in-a-hundred good run. Fret not though, pretty much any second or third wave will feel like a boss battle anyway. There's a fine line between challenge and frustration and Roche Fusion isn't that good at remaining on the good side of it.

I played for over an hour straight and I have no idea what I was doing. I was pretending to dodge bullets and I apparently did, for a time at least, and achievements kept popping on the bottom right side of my screen. The game does a really poor job at explaining anything to you, even in he pseudo tutorial which consists of a couple confusing screens full of bright colours. The thing is, that matches perfectly what you'll be up against: bright colours. I really wonder if there have been reported cases of epilepsia while playing this game because it's frankly too much.

There's a "souls" trend in gaming, so to speak, which favours games that hate you and Varstray is one of them. You're not armed with a toothpick for a change, but the sheer amount of bullets is just disheartening, and that comes from a shmup and bullet hell lover. WTF man.

After a quick glance at the options, where I found the "new!" above-mentioned tutorial I started the game in arcade mode and I managed to do a full two-loop run, which means 24 levels of pure aborrent hell and dozens of continues.
It took me over half an hour to find out about the different kinds of weapons, the shield and the super boost thingie that erases bullets and upon which the game seems to be built. Even if the early stages are a bit more doable than the rest, the controls did not feel intuitive enough and there's no respite from the unrelenting waves of impossible-to-dodge bullets to take ownership of the game without certain death.
One could argue I could have tried more, different modes etc... but that's my way of feeling a game: how does it play and feel out of the blue, without tinkering. Last but not least, for some reason there was no sound at all during my run.

All this led me to ask for a refund and this review. "I played for over an hour straight and I have no idea what I was doing." pretty well sums up my feelings.
