Good work on the game!
When I gain access to an L1, for example, it might help to have visual feedback, like maybe changing the door color, etc.
Not sure what the difference is between Damage and Infect. Stun works as expected.
The message when I get hit the first time, or for some enemies is also “L1 access granted”. This should be “Damaged” or something like that.
The player and enemy hitboxes were a bit confusing at times.
Nice to discover that there are different strategies. For some levels clearing out the enemies didn’t work well, and instead I had to evade and get to the finish.
The difficulty curve is good to start with. Some of the later stages got a bit repetitive.
Overall this seems like a good start, and could be developed further by adding more diverse mechanics/levels to keep the player engaged.
