Hi AntDesign!
Played your game for a bit, here are some thoughts: First of all, I really loved the character design his running animation is really nice! Maybe add a turning animation when moving to each side instead of gliding? Those pointy blades are great, do you consider to add some more traps and obstacles? some missing tiles for example? and maybe power ups? Regarding to your question, I prefer web build for those kind of games, but since it is unity Windows build should be pretty easy to achieve so why not. Also did you consider mobile build? Anyway I had a lot of fun playing your game, thanks for sharing!
Hope this review was helpful:)
Its title sounds cool bit like mystery but the game's descr. rather more about the keys than what could be about the game, maybe quite more spoilers or hints before clicking the run(game)-button would be awesome in being added there?
The visuals and graphics are cool, especially the vision from above, realistic walls (just my device quite lagging if games being directly played, downloads would be an issue of free space, anyway a youtube-tutorial like: possible right/wrong paths, possible encounters, etc. could be nice, which also being less laggy when viewing them).
I could add info if viewing streamed let's plays with cam too, details about sound, features, possible typos, etc.
