Thanks for your feddback :) Yeah well.. this was my first time doing level design and I was worried it would have been too easy.. so I might have overshooted it a little bit ^^'
If the game gets positive feedbakcs tho I'll work on expanding it and I'll try to recalibrate the platforming.
as for the last one.. it's voluntarily a little harder to find. on ehint would be... find the Hearthbeat and look around xD
