So I'm a huge sucker for scifi and this very obviously takes inspiration from metroid! I'm shocked you weren't in the classic category! The art looks great and cohesive.
However I ran into a bunch of issues with this game (itch won't let me post the screenshots, too big...);
Often I would leave a room, take an instant hit as I entered the next room and die
A room on the far right had a door that just restarted the game
This console (two floors up) crashed the game every time
Using the settings menu button causes it to become 'Selected/Focused' so every use of the spacebar opens the pause menu
These guys could get stuck like this, not sure if it's intentional (Tanks could get stuck on floor doors)
Not sure if this guy (Huge tank) is a 'come back later' but I couldn't deal with him or leave
minor: player and enemy hit sounds are the same, making it hard to know who got hit
minor: killing enemies seemed to serve no purpose, meaning I felt incentivised to skip them wherever possible
Unfortunately I just couldn't get very far due to these issues
