This was a good experience and enjoyable game to discover
The battle system is simple and you get the gist of it quickly.
You have two character one you can attack with and the other to support or use both in attack if they are both healtly (+1 point for skill descriptions with funny notes ^^). I found the game was easy once you understand which skills you need to spam and you only need to make sure you get potions to restore you if you failling the traps or failing to fully heal before finishing a battle. I had to reload several times on a particular floor for reasons I won't reveal here.
Although it could be only be me, I had difficulty to get used that Hit/Health point was called SP in this game (SP which is usually either skill or spirit as manna for using tech)
The general plot might be simple for some, but the charms come from the two main protagonists who are fun to follow and conversations are well made and never felt-forced. The art, cute chibis and several CG make you like the characters even further (Poor Trip who gets teased at every occasion to either Erakhos's amusement or changing the subject). I would welcome the duo back if they re-appears in future game ^^. I liked there was foreshadowing several points in the lab (or even previous) chapter that would important in later chapters.
The field skill is optional due having limitless HP regen in battle if play correctly. The Scout offers of interesting dialogue that can be missed if you're not using reloading to have a good stock of scout. The minigame button entry came out of nowhere the first time, but I was prepared the rest of them : The fact that mini-game content was randomized each run/reload is a good thing to force me to retry several times before succeeding. The battle with the final boss was great to play (Won't say any spoiler so discover by yourself, people!)
Overall, I had fun playing the whole game in two sessions. I hope you people will give it a proper chance to play it yourself.
Thanks for the creator for making this game ^^
