Hey, DernieresPensees! This is quite challenging and fun. I like the level of polish. The audio is good and the visuals are also really clear and nice. I like that information is being clearly provided regarding enemies' behaviour. The movement and gameplay felt consistent enough, and I had only myself to blame every time I failed.
Personally I found it to be a steep learning curve. Then again, I do not play a lot of fast paced action games. In 5 minutes, I was able to beat the final boss only once in easy mode. It did help a little that the enemey attack patterns did not change- I could memorise a few things and anticipate what was coming next, but not so effectively. This is probably my own problem since I have potato memory and also get distracted easily. The furthest I could get in medium difficulty was surviving about 3 or so seconds of boss. I tried hard mode once and died in less than 5 seconds.
Here are a few things for you to consider.
1. When the character dies, allow pressing of restart button with spacebar key since my finger is already on it and it is easier than having to move the cursor to the UI or moving my finger to the Enter key. Since constant retries are a thing here, you want to prioritise convenience.
2. Reduce the area of effect for the moving bombs since there are two of them at the same time and very few safe tiles available. Alternatively, you could add another half second of aniticiaption time showing the area of effect before they explode.
3. Add friendly fire to the enemies so that I could go near another enemy to attract a projectile towards it or have a moving enemy walk onto a dangerous floor tile, and smirk about how smart I am.
There is enough information being provided but not enough time to react, but I don't play a lot of fast paced games like this, so I may not be your intended target player. However, you could try and include players like me with the easy mode. Overall, it felt pretty polished and it has great potential. Nice work! I look forward to seeing what you come up with next!
