The art style is pretty cool. Personally, I'm a sucker when it comes to anything related to robotics.
Now for the gameplay issues...
. I never quite felt that form of exploration/discovery present in most metroidvania, but anyone can easily overlook that. so, this isn't much of an issue, just a personal though.
. The controls, the controls. Please fix them ASAP. You'd also do us a lot of good, if you fixed the gameplay issues in level 2, cuz it appears that's where most of us end up stuck at.
Overall, it's a game with enough potential, once you've polished the minor bugs and small gameplay issues, I feel I will enjoy this game a whole lot better.
