I liked the sprite/artwork, the movement was cool and the dash was fun.
Health regeneration was a little confusing/hard to tell what was going on. I noticed the large enemy helped with that. I was also a little confused about pressing F to enter the room/new section as I didn't understand what it was I was entering and made me wonder if I missed other routes/areas because of that.
I did feel that I kept getting softlocked near the end when entering a room with 3 levels not being able to jump 3 tiles high or get to the lower level, however I did manage to pride myself in beating the larger green enemy which was nice hidden touch.
But still super cool you managed to put it up/finished the jam in time as I found it hard myself to finish the game jam :) Good work!
