Alright, I'm posting this here because this was the last of Kyrieru's games that I played. Sorry but I gotta rant...
This guy needs to stop making games. Of the three games he's made so far, none are fun to play. Don't get me wrong, the art, animation, and music are awesome. However, the gameplay/game design is terrible. Eroico is the only one I beat and I refused to play more of the other two.
Let's start with this one, Kurovadis. There's not even a map, which is pretty standard in these kinds of games. Controls are bad, a theme for their games. Platforming offers little leeway and often has blind jumps/drops. No i-frames is asinine. Enemy placement makes for too many BS moments where you literally have to get hit. Losing a power-up to getting hit is dumb, especially for the point above, and also is a theme in their games. Of course, the lack of a gallery for this game is especially dumb. Lastly, I only made it to the boss in a bubble before I quit.
What a terrible boss. It doesn't utilize your abilities at all (rolling through his attacks is ineffective since you can't roll through him and his attack is 1/3 of the arena length, and wall jumping is barely different than just jumping over him). Also, only doing 2 damage regardless of your damage is ridiculous. I got his health down to 1/4 and he still had his bubble. Is there another phase? Does he die immediately when his bar is depleted? No idea. Don't care to take 20 minutes per attempt to find out. Most Dark Souls bosses don't require this level of grind to beat. Between the lack of gallery and the wall that is this boss, I have no interest in playing more.
Aster is similarly problematic. Controlling the ship is ridiculous enough on its own but add in that sometimes the boost doesn't adjust to your change in direction and bumping into something sends you flying in the opposite direction and I want to break my monitor. Again, losing your power up to a hit is stupid, and if you spend money on stats and don't reach a checkpoint then the money you spent and the increase is gone. And scenes only unlock if you reach a checkpoint after seeing the scenes in-game. But at least there's a gallery system and I can get people's full saves.
Eroico is easily the best of the three. However, many of the same issues still persist but just to a lesser degree, like terrible enemy placement, losing power-ups, the controls being slow or wonky, too precise of platforming, blind jumps, and terrible bosses. Again, I beat this game because it's problems are less egregious than the other two, but that doesn't make it good.
Can I also point out that there is ZERO story in these? I get it. It's a porn game, but I like story. And if you're going to make a stupid-difficult porn game then why can't you take 5 minutes to insert a few lines of dialogue so that I know what the fuck is happening and what the objective is? These aren't ports of '80s games without the handbooks for crying out loud.
TL;DR
Kyrieru is a great artist/animator/musician but really needs to leave the gameplay aspect to literally anybody else.
I think he's got a fourth game in the works and maybe he's learned something at this point, but I won't hold my breath.
