I liked the spritework in general, but animations felt weirdly placed. Also, there's no impact or indication to attacks or getting hurt. UI and message boxes don't fit with the general artstyle.
The enemy and level design need some work. There's a part where you "need" the moonshot to kill a lot of owlmen, but if you used it before in some other level you have to die to recharge it with the initial enemies. Except the "mage" and the final boss, owlmen don't feel like enemies at all. I was starting to question why I had to kill them, being so docile, hahaha
Audio was ok. I don't have any comments about that.
It's cool that you managed to make a boss fight and that was what I liked the most. The attacks are telegraphed well and the amount of challenge feels right. Wished there was some indication that my arrows hit the boss apart from the healthbar going down.
In short, this looks good but feels a bit off. I'd say it has potential.
