I like the simple and clean visuals. Core gameplay on theme for the jam.
The "tutorial" was a nice way to teach how to get new abilities.
Having that little animation before an enemy spawns is also nice, to plan ahead where to move.
I couldn't get past the attack skill though. Only once I saw a different enemy, but couldn't get close enough to get hit by it to get the new ability. I got swarmed and died to one of the first enemies.
The attack skill is quite tricky to use as it doesn't hit in a straight line and leaves a gap between the target and yourself as a safe zone, so you really need to keep the right distance to the target for it to hit.
Good game!
