This game has potential and it's pretty nice (? really like the game, my only suggestion is that the second boss didn't give any instructions to beat him, I mean people can get away with not giving instructions but usually because you can guess (sometimes you gotta be smart about it and it isn't obvious), you just threw a new mechanic out of nowhere and expected humans to know about it, should had added some texts saying probably some dialogue giving reason to make the main character activate his shield, and for him to know that's how he can beat the enemy, then say "press space to activate shield"
I really like the game, probably camera isn't good or you made it like that on purpose, and hello again mate
