How I love the n64 aesthetic, and this game captured it really well! The visuals and mc design are super nice, and contribute so much to the vibe of the game! I thought that the mechanic of having to shoot enemies with the opposite color is really cool too, and makes you think before you shoot instead of getting away with spamming a shoot button [:
Movement in these kinda games are always a bit tricky to nail, but I think that the movement was in general pretty nice! If anything, I think that the jump could have been a bit faster - when I look at Spindo I imagine he springs up and then falls down kinda heavily :b
I understand that time constraints were tight for this, but I think that the player experience would be really enhanced by adding some kinda music or ambient track as well. All in all, I really enjoyed it, and I love to see these kinda n64 style games!
