Pretty interesting take on the theme, but I ultimately thought it was a bit weak on the interpretation, since it was just a reskin of a health bar. With that said, I also see that the RAM usage would also tick up when you don’t take damage or do anything, so maybe it also relates to the number of enemies in the level or something similar? I hadn’t figured that part out yet.
On the gameplay side, it was pretty simple. The controls are ok and bug-free, but I found that having everything in the game suddenly stops to give you an upgrade panel is kinda jarring.
I also found out on the second run that this game was randomly generated, so I have to commend you for that, but sadly I feel like it’s still missing some meat on the bone to make it feel really interesting.
