Hey that was really fun :D Its increadible how much you created in one week ! Also gaems with checkpoint are hard to find in gamejams so extra points for that :]
For some reason the part where windmills are was really laggy you should look at that :/ Also the artstyle is not coherent enough but thats just my personal opinion :p
Overall its impressive you have packed a lot of mechanics in a one week game good work !
[Edit : I reconized that you were in Blackthornprod Game Jam 3 nice proggres :D keep it up !]
