Impressive for a short jam like this!
The gravitational pull could be easier, as well as spike size/position adjusted at times. In a fast-paced game like this you want more "bapbapbapbap jump, dash, mess with gravity" rather than "ok, I hit a spike, restart x300 times". But as mentioned, very impressive! I like it a lot!
