its fine but i feel like you could give us a chance to fight the virus or at least explain we're gonna have to redo the whole level if it touches us?? maybe at least have the bolts already collected? idk i dont have the patience to play thru the level again when i already backtracked several times to make sure i got everything/ check out what all the switches did, only to end up being cornered because i spent like 30 extra seconds trying to sshoot an enemy that was flying too high up to shoot at first (maybe allow us to shoot upwards???).
i think it'd be fine for the game to work like this so long as you have a few simple introductory levels to show the player what each block or unit does, or at least let you know you're being chased by something instead of just playing that music??

I like how you manage to keep me interested yet this game is not my type of game but I like the 8-bit artwork a lot sorry about the 3 stars it's just there should be more lives at least and it should have like a boss make a second if you follow these I would love it but this game is not bad just telling you

I like this game. ALthough I found it a bit irritating when I had to start over after being killed while trying to grab the last bolt..Still like it pretty much!

This is a cute little game its not my cup of tea personally but i found it annoying how i had to restart every time after i died i found it kinda annoying but other then that i say no problem with your game keep up the good work
