I completed the game and really liked the global idea. I love the console esthetic and your design. It's really striking and efficient.
The game design is interesting but a bit weird:
- the start can be really confusing: I started my first two fights against blobs and I couldn't win those so the start is a bit random. I think the first fight should be forced a phantom on the first run so you can at least progressed a bit. Starting a game and instantly losing is a bit frustrating
- the whole sector 1 phase is mostly grinding to get DM until you get sufficient stats. This is ok since you'll chose your path to upgrade as fast as possible. At this point glucose is useful only to regen and try to last one more fight
- Once you feel powerful enough evolving is useful to fight boss with the best stats possible, since it's not transmitted to the last you want this only if you want to progress to the next level.
- fuel is in a weird place, you actually need only to grab one fuel to get to the boss on phase and that's all since you're not gonna last much more than 1 level since you don't really have way to regen and grinding fuel on top of fight stats
- I could imagine that you could have a lot of fuel to go all the way, have efficient stats for boss 1 then go really powerful by evolving on the way. But the number of EL required would end up really high and if for some reason you don't get a lot of glucose you're probably doomed.
so basically my run went: grind a lot on level 1 -> beat boss -> (grind a bit -> beat boss) repeat 3 times
Maybe if fuel cost didn't augment at each level it could be worth it grind it a bit to try a two or three level break through.
Concerning stats membrane/hp I think having a way to regen a part of it after each fight could have make it more interesting. I feel like you don't need membrane as much as you need atk and speed since you can't regen it (except with glucose when you have no DM choice).
Sorry that's long but you asked for feedbacks ! They're my opinion which is probably biased by my strats. I really enjoyed the game despite the grind at the start.
