I love this game, I love how it's played out, how you gain more the more you play and how it reminds me of Megaman series and give me the Metroidvania vibe. The pixel graphic is charming, color theme is great. Super decent work (despite some minor issues), I love damn game man xD.
If possible I'd love to be able to play more of it or learn to make one :D.
Love your work, it makes my day.
Well done <3 !
