The main time mechanic is really cool i was thinking of making same thing but eventually boiled it down to more simple version i like how you put the tutorial text into the walls and i also like the overall vibes of the flash game that it gives now there's a lot of potential in that idea and i'd love if you keep updating this game (pretty sure speedrunners would love it too) i dont know what other mechanics there are since im playing from phone and because of that i got softlocked on first shooting lvl cuz i couldn't find the shoot key but i'd suggest you to add something that you would recive if you actually hurry up while playing for example some colectible or maybe some kind of secret challange lvl
