This was such a good entry, it deserves much more recognition. Controls were extremely responsive, the design was superb, graphics and music was so good that honestly I think it is better than many successful games on Steam.
You get all the "standard" upgrades you would get in a Metroidvania game but even them each of them has a little twist to make it unique.
If I had to find a flaw in the game it's that the difficulty spikes up a lot for the final boss, I never died until then, and then the boss took me around 15 tries (just tuning down damage from 3 to 2 I think would suffice).
This was definitely the best game I played in this jam by far.
