Fun game and awesome graphics. Somewhat reminds me of speeding through a level in Neon White.
Isd there an indicator for which enemy is the key enemy? It was frustrating going through a level for the first time trying to figure out who had the key.
Also the health constraint made it so I barely ever grenade jump unless it's for a huge time save like jumping over the maze. Maybe the grenades shouldn't do damage to the player to promote nade jumping since it's such a fun part of the game.
