Congrats on completing the jam! I got as far as the spiral level - not sure which one it is.
I think the art and music match well and gave off a good old-school vibe. I liked how you built very different levels out of a few basic mechanics.
Some comments:
- Font choice was difficult to read
- It was hard to see the holes the arrows were coming out of. Perhaps it needs like a grey border around the holes seen in other games.
- The spiral level is not difficult in terms of understanding what to do, but the timing for getting through the explosions is way too tight. I would often get to the last one and then blow up.
- I also found that the arrows/explosions were a little too sensitive. Sometimes i would not be touching them and blow up on the tile beside them.
- It may help to have a SFX for ticking down when you hit about 5 - 10 seconds left to encourage the player to hurry up
Great job!
