I love stealth games, and there are not enough out there. I really like your attempt on making a 2D stealth game. The switch when switching to the "invisible" mode is a good idea. With a bit more polish this game can be quite fun. The controls feel floaty and not very responsive. Also some collisions with the enviroment were a bit buggy.

Music was fitting,

Overall, great job!

The concept of the game was refreshing.  Stealth 2d game was totally unexpected, and welcome.  It played well, but I hated the sorta see through floors.  Sound effects would have added a lot to the ambiance.

i  liked the game a lot. just want to mention that there was a bug where if i kept pressing forward on the side of a platform and jumped again i was able to get on to the desired platform. also i felt the invisibility mode was a little overpowered, maybe make it so it doesn't last so long. other than that, i like how movement felt fluid, if you are accurate enough (like how  a ninja would) and really like the idea of player moving around on a comic book page. really can't wait to see if you flesh this out more!

Nice, but waiting for platforms is a little bit annoying. Am I right that it is a "comic book" setting? Or it's just looks like.
