Had my interest until I survived my first minute. Then I saw the boss fight and immediately knew I was going to hate it. Spent an hour or so getting all the upgrades and just can't seem to kill the boss so... Was a solid 4/5 when I started but now I doubt I'll ever take a second look.
There is a video on YouTube with a playthrough and the winning strategy, the idea is to dash and always kill a dasher while hitting the boss. So try to lure the dashers where the boss will land and then hit all of them. Killing dashers recharges the dash so that you can get multiple hits in each time and/or escape
