Okay so after playing for a while I found a few bugs.
1. The blue demon demolitionist hit box is very broken. I can kill it from 2 tiles away sometimes.
2. The throwing star upgrade that teleports you is a bit broken. If you press it and the ninja star is not on screen you get teleported to 0,0 . Or if you tap it twice by mistake it will recall the ninja star and teleport you to 0,0.
3. The 🔥 will hit you one the turn it disappears.
4. The boss sometimes moves onto your ninja star.
Still a very playable game and loads of fun (leaderboard says it all)
Waiting for the mobile download after the Jam 👍
