Fun game! I found a couple bugs (listed below) but nothing game breaking. I also have a couple suggestions for game clarity.
- If you don't maximize the game, the UI overlaps and goes off the screen
- I managed to get the first attack to hit two enemies at the same time, not sure if this is intended
- It can be hard to know when the player is taking damage, having the sprite flash red or something like that might help.
- I had a hard time knowing when my abilities would fire, maybe adding a visual cool-down in the top left would help me plan when to turn around and fire at the enemies (This could also be a skill issue).
- I'm not sure how the jam jar is targeting, but I had an instance where I had one enemy to my east, and one to my south. The jam jar fired straight south east and missed both of them. If you're finding the average of nearby enemies it might not work well. One option would be to find all the positions of enemies rounded to the nearest 50 or 100 pixels and pick the most populated location.
- Not sure if it's intentional or not, but if the chance to double your upgrade is proportional to the area of the slices, then on average you'll get less than just taking the standard upgrade. Meaning the safe option will also get you more upgrades in the long run.
